Like its stable mate, this new Smart Kit is a 3-in-1 offering, allowing an M3, M3A1 or M3A2 halftrack to be built. Dragon has spared no effort in reproducing these three distinctive vehicles. The essential differences are these: the M3 was armed with an MG on a central pedestal mount; the M3A1 replaced this with a ring mount in an armored ‘pulpit' above the front passenger seat; and the M3A2 was a prototype with an armored shield on the AA ring mount , with moveable stowage boxes in the rear of the hull. Requires paint and glue (not included).
