001: Italian Carro Armato P26/40
The gun tube is very much the same as in image 001 with the exception of the muzzle cap. In addition, the sloping side armor on the upper hull and the drive sprockets are the same as every picture I've seen of the P26/40.I think 003 is actually an Italian M14 or M15. That Gun is not a 75mm...
Well done on all!006: U.S. Cletrack M2 Aircraft Tug
At least three KV hulls it would be great going in a straight line but absolutely no chance of turning at allThat's a fake. Built from 2 KV hulls, 2 KV-1E turrets, a KV-2 turret, a T-26 m33 turret, a T-40 turret and what looks like a T-38 turret. The hulls look like from the Trumpeter model range.
Correct on REME. Also, the anchor insignia painted on the vehicle was the sign of the Beach GroupsOK, found a colour drawing. It's blue, yellow and red (top to bottom), the colours of the Royal Electrical Mechanical Engineers (REME).
