Italy OOB 34 corrections/suggestions (v.8.1)

[Griefbringer]

On an unrelated note, I happened to be taking a look at Italian weapons today, and noticed some odd values. Here is a list of them - these should be pretty straightforward to handle.

1.) Weapon 12 (37mm L33 Mod.21) has HE kill 2, while other 37 mm guns have HE kill 1.

2.) Weapon 61 (Obice da 75L18) has warhead size 5, HE penetration 3 and HE kill 11. Other 75 mm guns have warhead size 4, HE penetration 2 and HE kill 5.

3.) Weapons 64 (90mm L53 Mod.21) and 65 (90mm L53 Mod.39) have HE penetration 3, while weapon 90 (90mm Mod.39 HE) has HE penetration 4.
I would rather expect HE penetration 2 for all of these guns.

4.) Weapon 72 (105mm M6 Mrtaio) has HE penetration 1. I would usually expect HE penetration 2 for mortars of this calibre.

5.) Weapon 79 (Ansaldo 149L17) has HE penetration 4, while other 149 mm guns in this OOB have HE penetration 3.
