Welcome to the Strelets Forum. Please feel free to discuss any aspect of 1/72 scale plastic figures, not simply Strelets. If you have any questions about our products then we will answer them here.
WW2 Italian Field Artilery is an big gap and Strelets have given us some great artillery sets for 19th/20th century conflicts recently so hopefully will consider this set too. Also yes to Italian Infantry in sun helmets and maybe also a set of Italian Askari ( Libyan for North Africa or Eritran for East Africa) as these troops made up a large part of the Italian forces in Africa.
Here's another vote for WW2 Italians, and field artillery in particular.
Apart from metal, there are field guns (of French and Austro-Hungarian origin) available in styrene but the 75mm Cannone da 75/27 mod.06 is lacking. It could be used for WW1, WW2, the SCW, and in many armies since their Krupp guns are very similar.
