Another secondary user - Finland.

Finland acquired the first 12 guns already just before Winter War in October of 1939. Finland purchased another 12 guns during the war from Sweden. Also Swedish volunteer unit SFK (whose weaponry was financed with donations gathered in Sweden for Finland) arrived with 12 guns. When Sweden loaned further 24 guns to Finland during Winter War the total number of these guns used in Winter War reached 60. 24 guns were returned to Sweden and the remaining guns were used early in the Continuation War - survivors were used as coastal defence guns in 2-gun batteries until the end of WW2.

Max. range:

Recoil: 1.35 m

Elevation: + 16� 8' / - 10�

Traverse: 3� 30'

Track: 1.48 m

Transport: drawn by 6 horses

"The Krupp gear in question is applied to an ordinary 75mm gun with a wedge breech-block actuated by a vertical spindle. On the lower end of this is an arm projecting laterally, terminating in a knob which strikes a projection from the cradle when the gun runs up or back. On recoil the projection yield and lets thje knob pass freely; during the last six inches of thye run-up the projection arrests the knob, forcing the spindle to revolve and the breech to open, in which position it is hel by a catch connected with the extractor till the next rouns is inserted, when the breech is closed by a spring. It is is clear that the action of this device depends upon the gun running up correctly, and according Messr. Krupp use somewhat elaborate check-buffer to ensure a smooth and complete run-up" (The Royal Artillery Journal, 1914, pp. 1-2).

I have no data about the shell and shrapnel, but they are probably the same employed by standard Holland field guns.

Thanks - that's great info.

I've been doing a bit of digging - I had a vague memory the Krupp guns were recycled as a close support gun.

Memory didn't fail me: Canon de Infanteria C.75mm "Matorras" - 1945 - designed by Lt. Col. Matorras - built from shortened Krupp barrels with a

locally developed carriage�which seems to be influenced by the WW2 German IG 18. The Krupp breech block was replaced with a Maxim-Nodernfeldt type which

according to one website had a quicker action than the Krupp breech. The gun served in the Argentine Army into the 50s.

My dad did his military conscription as advanced observer and radioman for the Artillery in 1955, and they still used them. He didn't recalled them with much love, as they used to have a rather haphazard range...

CharlieC · Legend

Thanks for the contribution

Notice the interrupted screw breech - not what one would expect on a Krupp gun.

I've read that Argentina held field gun evaluation trials before they ordered the Krupp gun. I suspect the Argentine Army requested that Krupp should

modify the standard 75mm. There is a Krupp patent for an interrupted screw breech dating from about 1905 which looks like this breech. The 75mm Krupp

Gebrigskanone M1908 (the one for the Japanese) seems to have used the same breech design.

It would be nice to know how many guns Argentina purchased and how long they were in service. I have a recollection that some of the 75mm Krupp guns

were reworked as a close support gun in the 40s(?)

Here's a 1909 Krupp gun in Argentina. I have seen several others in parks or guarding the entrance to military buildings. This one, believe it or not, is in the entrance courtyard of a confectionery factory! As you can see, all the engraved legends are translated to Spanish.

This is a worthy subject, �.. I will participate. � I have a file somewhere with a few sketches that are mroe than 10 years old; �I'll try to dig them up.

As noted in another thread there isn't any single source of information on these guns.

Rather than try to accumulate all the information on these guns and probably get it wrong in various ways I thought we could try a colaborative

project. If you know anything about the 75mm Krupp guns please contribute - anything will help - images, refs, etc.

Once we have a reasonable amount of info I'll wrangle it into an article for Landships II.

Just to kick things off - here's what I know about the Turkish 75mm guns.

The Ottoman army acquired 75mm guns in 4 orders before WW1 plus a batch of ex-Brazilian guns in 1914 and captured Rumanian guns in 1917.

The orders were:

1904 - 96 Model 1903

1905 - 462 Model 1903

1910 - 90 Model 1909

1911 - 88 ???? (haven't seen a survivor of this order - anyone help?)

The Model 1903 guns were a mixture of foot and field artillery with a screw actuated sliding breech. There is a prominent fore sight on the left side of the

reciever.

The Model 1909 guns had the same sliding breech block as the FK 96 n.A - the survivors in Australia all have axle tree seats.

The pre-war guns were processed through the Imperial Arsenal at Istanbul and were remarked in Osmanli script. The gun numbers are in sequence

through the orders. Judging from the dates inscribed on the guns the 1904 order guns were processed in 1905, the 1905 order was processed in

1906-07. The dates on the 1910 order guns all seem to have been processed in 1910.

The batch of guns in 1914 (40 or 54?) came from a Brazilian order seized by the German Army at Krupps. The Brazilian guns were designed to fire

a heavier shell than the standard 75mm but could fire the standard 75mm round.

An unknown number of Rumanian guns was seized/captured by Turkish divisions fighting with the Central Powers. Rumania collapsed in March 1917 and one of the divisions

(26th) was posted to Palestine. The Rumanian guns were similar to the Model 1903 except that they used a Rumanian designed panoramic sight.

There is also an additional handwheel and small gearbox on the right side of the receiver - this moves the sight bracket via a series of rods according

to a restorer of one of these guns.

The Brazilian and Rumanian guns retained their original markings.

Lots of images, etc at:�http://www.ammsbrisbane.com/home.html?L0=2&L1=4&L2=0

Charlie
