German artillery pieces with low HE penetration

[Griefbringer]

Doing some more delving into the German arsenal, I found a couple of artillery pieces that had HE penetration ratings that seemed slightly lower than usually seen for guns of given caliber. These were the following:

Weapon 036: 7.62cm FK288(r) - HE pen 1
Weapon 053: 7.62cm L41 F-34 - HE pen 1
Weapon 063: 8.76cm FK280(e) - HE pen 1
Weapon 069: 10cm K18 - HE pen 1
Weapon 070: 10cm leFH 30(t) - HE pen 2

Based on other similar weapons, I would have expected the first three weapons to have HE penetration of 2, and the last two weapons to have HE penetration of 3.

I've put this on the list to look at this winter but looking at the first example there is a descrepancy between the German FK288(r) and the Russian Zis 3 which I will need to investigate

Checking the Soviet OOB, there is also a discrepancy for the second gun on the list (7.62cm L41 F-34, main weapon on T34), which has HE penetration of 2 on the Soviet OOB.

8.76cm FK280(e) also seems to be a German designation for the 25 pounder, which on the UK listing has a HE penetration rating of 2, so there is also a discrepancy with that.

As fpr those 10 cm weapons, I am not entirely sure what to compare them with. Were they original German designs, or did they come from Czech factories?

10cm seems to have been a popular Austro-Hungarian calibre.

See e.g http://en.wikipedia.org/wiki/Skoda_100_mm_Model_1916

Post Imperial breakup then they of course ended up with all the former constituent states and others, under umpty-five different designations for what was the same thing.

Hmmm, for some reason I did not think about the possibility of Austro-Hungarian designs - makes sense. A bit embarrassing, considering that I have even spent a day visiting the impressive Austrian military museum in Vienna.

Taking a look at the OOBs, there certainly are a lot of 10 cm howitzers of various types in usage by different countries around the former Austro-Hungarian empire. This also means that the Germans could have ended up with captured 10 cm howitzers from a lot of sources (eg. Austria, Czech, Poland and Yugoslavia) - and a plenty of work for the ordnance officers trying to keep track of all of the different guns in the inventory.
