A Beretta SMG should be a pretty simple conversion taking a plastic rifle of your choice or maybe a plastic PPSH -41 and adding plastic rod and a magazine from plasticard.
I love this list, you guys are fantastic. Thanks a million. I never thought about sculpting my own Berettas but now you have got me hooked.. use a plastic rifle for the stock and then add rod and strip... uhmmm
And yes, I could use the lovely Warlord paras for the Nembo, but the "F" Recce Squadron (aka the Italian SAS) wore a British smock with Italian insignia and used a Beretta...at least from what I could figure out...
