This small cannon should be the least known of the Chilean Army, as its caliber is not commonly used by this Army, and served at the same time as the mountain gun and field gun Krupp of 75 mm M / 98 which were much more known-
.
They were the political response to the purchase of the Krupp guns Model 1898 of 75 mm by the Argentine government, but they used a different breech block system at the Maxim-Nordenfelt of our Army, these guns Chilean they used Leitwell breech block system.
The Krupp factory produced weapons according to what they were asking its probable clients (breech block, caliber, etc). Chilean army used four different breech block systems in their guns Krupp between 1879 and 1910 (two Krupp, one Leitwell and other Ehrhardt) and Argentina used five their guns Krupp between 1880 and 1911 (two Krupp, one Maxim-Nordenfelt, another Welin and finally another Ehrhardt).
The 70mm Krupp had the possibility to target in elevation and direction and overall (except for the breech block) they were resembling at the Argentines.
There are several preserved in museums or Gate guardian
I do not know because the Chilean Army had at the same time and for the same service, two guns of the same factory with the same characteristics but whit two not very different calibers. But Krupp was able to provide without difficulty weapons of any caliber from the 40mm to 305mm.
So when Mr. Brunner says:
…..Or do you really thing Krupp was willing to manufacture two identical guns in two different calibers only a few milimiters iapart? (e.g. 238 and 240 mm Ogf course not!!! discussion is very much a propos….
is another silly answer.
Because than Krupp is a factory that produced simultaneously guns for exportin caliber 75mm and for the German army in caliber 77mm, ordid howitzers 120mm and sold to Russia 122mm howitzers, etc. etc
The reasons for these differences are more than known to all fans of historical topics artillery.
