Hello Bish, Griffin25, Cliff, and Steve - thank you all for the positive comments.

Brach Models is an Italian based company, and they do quite a few resin subjects, including full kits, but they are pricey.

Yes, this tankette was not an ideal vehicle for WW2, it's design actually goes back to 1929 and the British made Carden Lloyd (which eventually became the prototype of the Universal Carrier).
The Italian Army wanted something small that could be used in moutainous regions, plus the vehicle itself was only intended to support infantry against enemy infantry. No doubt the cramped interior did not help in hot climates, nor did those leather jackets issued to armoured crews. There was also a height restriction put on crews for many designs of Italian armour, I think the cut-off was five feet?

The paint scheme is based on period b/w photos combined with literature. Pictures taken from around the time of Operation Compass (1940), appear to have dark finishes, which are likely pre-war shades. Many reference books suggest some desert paint was used before an official colour was arrived at sometime in March 1941.

Jack
