Dragon have released the '3 in one' Ausf D that has the 251/1 Falke with IR Gear - I won the kit at my club's raffle on Saturday - and it also comes with IR gear equiped grunts. That can also be made with the 251/9 short 75mm howitzer, in the late raised mount, as opposed to the early one on offer from Tamiya.
DML's Second '3 in one offer' builds up as the standard infantry carrier, the 251/7 Pioneer version as well as the 251/10 3.7mm Pak 35/36 armed vehicle (low gun shield).
Then there is the 251/22 Pak 40 armed one coming from both DML and AFV Club.
All I want is for someone to do the 251/17 Lufwaffe 2cm Flak test vehicle to make me happy.
