Here is the look I cobbled together for the Italians. I'll break down what I used and what they are substituting for, incase anyone is interested.
NF mod has two pieces of Italian equipment; the M33 helmet and the M38 Carcano carbine so those are obviously used.
Uniforms are the variant of the Norwegian uniform that has this teensy bit of green tint to it. Some of the Italian WW2 uniforms were greenish-grey.
Belts for the riflemen are the Norwegian rifleman belts, SMG mag pouch is a soviet one for stick mags and the officer has a Finnish officer belt. For bags I've used Finnish bread bags and gasmask bags.
M31 SMG is standing in for the Beretta Model 38 since the stock and receiver have some resemblence. Used with 20 and 50 round stick mags since the Beretta 38 had 20 and 40 rounders available.
For pistols the the Finnish L-35 is standing in for Glisenti Model 1910 they share a similar looking profile and the Walther PPK subsitutes for Beretta M1935 and the Ruby pistol since all of them are pocket pistols in .32 ACP.
For LMG I went with the Madsen LMG since wiki claims[with citation needed] there were Madsens used by Italy chambered in 6.5×52mm Carcano. I was unable to find any pictures of said 6.5 Madsens or Madsens with Italian soldiers but whatever.
For tanks I was thinking this:
T-26 for M13/40 since both of them are based on the Vickers 6-ton (aka Mark E).
T-20 armored tractor for L3/33 tankette (aka CV 33) since both are tiny two man vehicles with forward facing MG armament.
T-38 for the FIAT 3000 since both are small two man MG only armed tanks.
And finally the Sdkfz.231 can stand in for the Autoblindo 41.
Also been having ton of fun make these scenes for the screencaps. The pose of the guy who's left of the officer is literally called "w_italian" in the animation viewer.
