These are some of my 15mm (1:100 scale) 3d-printed 1930s British Carden-Loyd MG carriers, printed by Shapeways in FUD resin.
This really was just a machine-gun
carrier. It was possible to operate the gun from the vehicle, but the arc of fire was very limited and the crew very exposed — the gunner would have had to have exposed himself fully to change an ammo box. That thing on the port side track-guard is the tripod for the Vickers. I'll use the stats for the Universal Carrier, except that these machines can only carry the two crew.
