Japan negotiated a licence with Krupp to build the 75mm Krupp field gun. Krupp probably delivered some Model 1905 pattern guns but the number of these is
unknown. The Japanese designated the gun as Type 38 (38th year of the Emperor Meiji's reign), some 2000 guns were built at the Osaka Arsenal. The gun
used a slide breech rather than the screw actuated breech of the earlier models. The barrel was slightly longer (2325mm) - it was referred to as an L/31 gun.
The Type 38 was used throughout the campaigns in Manchuria and China in the 1930s. It was supposed to be replaced with the 75mm Type 90 and Type 95
field guns but difficulties with the manufacture of these more modern guns meant the Type 38 remained in service in WW2. There are a large number of
surviving Type 38 guns in the US. The images are of a surviving gun at Modesto, CA. - the oval brass plate on top of the breech is the gun number.
(I guess I should get a translation of the Kanji markings).

Looking at the surviving guns - there are a majority of the original Type 38 guns. My next contribution is on the Type 38 Kai - there were 400 of these produced - most of
them were converted from the original guns. This gives a 4:1 ratio of original to modified guns. A quick and probably unrepresentative sample is at: http://warmemorials.us/listing-007-artillery.html (guns in Wisconsin) - of the 5 Type 38s documented only one is Type 38 Kai.

This is a very interesting image because it seems to show an unmodified Type 38 model.
All publications I can access (like http://www.ibiblio.org/hyperwar/Japan/IJA/HB/HB-9.html#III) agree that encountering a Type 38 gun in its original form in WW2 was very unlikely since most were updated to increase range.
Most interesting. Wikipedia and others say 400 of the improved type were produced but older guns were upgraded, so the total number of "improved" ones should be much higher than 400.
However clearly not all were updated. U. S. Department of the Army pamphlet no. 30-4-4 on Axis artillery says both the original type 38 and the improved version were in service with the Chinese Communist army at the time of writing, 1955.
The deficiencies of the 75mm Krupp design were apparent to the Japanese and a modified gun was produced from 1926 to address the lack of barrel elevation
and the consequent lack of range.
In part this was done by the use of a new box trail, however, the Japanese went much further in updating the gun. The trunnions were moved rearwards which
means that the breech is in roughly the same position for loading regardless of barrel elevation. A pair of equilibrators was added to reduce the loads on the elevation gearing.
Some 400 Type 38 Kai were produced at the Osaka Arsenal - there is some contention whether these were new production or remanufactured Type 38s.
The gun looks only superficially like a standard 75mm Krupp - the images are of a fairly battered survivor at Cadott, WI - the gun shield is missing which means the changes
compared to the original gun can be more easily seen.

In terms of German Krupp exported 7,5cm guns, I have a Krupp 7,5cm. Gebirg Kanone L/13 (Mountian Cannon) exported to Chile in 1891. This same type also was exported to the Ottoman Empire and saw service in the German Colonies.
According with Loebells Jahresberichte 1910, Uruguay bought 3 batteries of Krupp 75mm field guns.
In addition 24 Krupp field guns were bought by Spain in 1900, they were employed also during the Civil War: 8 were assigned to the Republican 3rd heavy rgt of Santander.
Here's a few notes I made from more than 10 years ago. I'm guessing they are reasonably applicable to this tread. To me, the splinter shield variations were interesting. Please note the splinter shield "hoods" also varied; some full size others cut back. Also the axle tree seat rails changed from model to model.
The barrels on the Dutch 75mms were heavily engraved with a motto and royal cipher of Queen Wilhelmina. As well as the 204 guns received from Krupp the Dutch State Arsenal
also built 100 guns.
The Dutch 75mm guns were rebuilt starting in 1926 to increase the max. elevation. The company that rebuilt the guns was HiH (Hollandsche Industirn Handelmaatschappij)
(later HiH Siderius) which is an interesting story in itself. Under the Versailles Treaty Germany was forbidden to have armament manufacturers. Rheinmetall relocated to Holland
buying out HiH and remained in Holland until the 1930 when it sold the majority holding to the Dutch Siderius company . The HiH rebuild of the Krupp 75mms resulted in a gun
which looked very much like an 7.7cm FK 16 with a short barrel. Notable was the relocation
of the trunnions to the rear of the gun and the trail was opened out to permit the gun to recoil safely at high elevations. With a modified shell the 7-veld had a max. range of
10,000m. Some 280 guns were rebuilt by HiH.
The story of HiH and HiH Siderius is documented at: http://www.overvalwagen.com/HIHSiderius.html
A further modification to permit the modified 7-veld gun to be loaded onto the tray of a truck was to make the rear section of the trail foldable. It's not known when this modification
Hopefully this swarm effort will find the final word on the question in which numbers the Japanese model 38 guns in their orginal form were employed in WW2. The following 112 pages volume leads to the conclusion: They were few.
The "Japanese Field Artillery" volume of the U. S. Military Intelligence Division, published in October, 1944, is available online.
It portraits quite a lot of Japanese guns, but while it details the improved model 38 (including five images) it doesn't do so for the original model 38. It also says: "Until the Model 95 75-mm gun was found on Saipan, the only 75-mm pieces that forces have encountered on a large-scale have been the improved Model 38 and the Model 94 mountain gun." (p. 29)
It gives around 1915 as a starting date for the model 38 improvement programm and says elsewhere: "During World War I the Japanese made major modifications in the construction of the Model 38 (1905) 75-mm gun. The piece was trunnioned forward and equilibrators were added to compensate for muzzle heaviness. The plain box trail was modified into an open box. This allowed for an elevation of 43°. Axle traverse was retained, thus limiting the effectiveness of this piece as an antitank weapon. The hydrospring recoil mechanism also remained, but was made variable to permit firing at high elevations. Although the Japanese have produced far more modern 75-mm guns in the Models 90 and 95, there is little evidence that the Improved Model 38 has been generally replaced as the standard light division artillery piece."
"From 1915 to 1930 large-scale field artillery production was apparently confined to the Model 4, the improved Model 38, and the Model 41 (1908) mountain gun." (p. 27)

The original model 38 makes an appearance in the chapter about "Obsolete or Obsolescent Equipment": "Certain Japanese artillery weapons, first standardized in 1905, are probably no longer in general use among frontline units. These pieces, the Model 38 series, were manufactured in four calibers-75-mm, 105-mm, 120-mm, and 150-mm. (...) Although their ranges appear to be inadequate for use against a modern army, these pieces were still being employed by the Japanese in China only a few years ago."
I have been in two minds about adding this gun but I guess it was a rebuilt Krupp 75mm
In 1939 Turkey produced perhaps 200 75mm L/35 guns which appear to have used some components from the pre-WW1 75mm Krupp guns.
The origins of the gun design are obscure. In the 20s and 30s there was a relationship between the "Dutch" firm HiH and its successor HiH Siderius and
Turkey. HiH had proposed a further update of the Dutch 7-veld design with an L/35 barrel. There is no available documentation but the 1939 Turkish
design looks very much like the HiH Siderius design. HiH Siderius went bankrupt in 1934 so would have had no direct role in the Turkish design.
I've never seen any performance data for the Turkish gun but it probably was similar to the FK 16 n.A with a max. range of about 12,000m.
The 75mm Turkish guns served into the 1950s.
First image is an HiH drawing and the rest from a surviving gun in Turkey. The two cylinders projecting out below the breech appear to be equilibrators.
I think the swarm has been pretty successful on the Krupp 75mm. I guess I should start to pull it all together in an article - it's going to be big.
It would be great if it could include a spotter's guide to the different versions (like model 1903, 1905, etc.), much like your reply to my question in the earlier thread how to tell a 77mm n. A. from the 75mm guns.
28juin14 posted a very instructive sketch of the gunshield variants yesterday.
It is that kind of extra info that modellers and wargamers need, so including it would broaden the potential readership. Regards, Pat
Hello, I must say I love this post very much! After all, they were the main gun of Chinese artillery for almost 50 years... Few people know that China also produced its own copy of Krupp 7.5cm export field gun in early 1920s, although in modest numbers. We Chinese call them "Type 10". The most interesting things I read about Chinese-made Krupp 7.5cm field guns is that a few of them had barrels that can be screwed down to 2 (or 3, cant remember) parts in order to be easily transported in mountainous areas in China. I wonder if similar designs were used in other countries.
For unknown reason it's very slow and uneasy for me to post images on my computer, so I can only upload one photo that I think is the most interesting.
Take a look at this gun in Chinese Military Museum in Beijing. It is said to be a German Krupp 7.5cm field gun made in 1912. However, it can be easily seen that this gun looks much lighter than a regular Krupp export field gun, and has smaller wheels(you can compare it to the gun on the right - this is a "normal" German Krupp export gun). And it's definitely not a Japanese Type 41.
Can anyone tell me what gun is it??
P.S. This gun has a sliding breech block.

Taki (http://www3.plala.or.jp/takihome/) says the total production was 400.
I took the liberty to ask about this on the Missing Lynx Japanese Modelling forum. There was one reply: Taki himself confirmed his position: "400 were not new built, but converted from original Type 38. So, 400 are included in 2,000 of original Type 38."

Hopefully someone can answer your query about the gun in Chinese Military Museum in Beijing - but as to difficulty in uploading images, I suggest you try at some time removing (from your member profile) your "signature" image http://www.beiyang.org/wenku/images/PingYuenx.JPG for a posting trial without it. Linked images are always problematical (in more ways than one) and it may be the server overheads which are conflicting with your ability to post (other) images into the forum. You can always restore it if there is no improvement.
