Al very much nailed that response. Andy and Gearhead very likely did too. How I know is I recently bought one of these old Airfix 1/32 kits at the LHS (8th Army)
and was very impressed with it. Good proportions and details, instructions, insignia decals! They did NOT work with the other(1/35) figures going into my Dio however. A friend really insisted it might be possible and wanted to see so I built one of them up to compare :
The Airfix "Tommy" on left....One from Dragon(with replacement resin head) on right
Here with a larger 1/35 resin figure from Warriors. Almost works..til you compare helmets,ect.
This pretty much says it..Airfix left...DML on right.......just doesn't work. Maybe the Airfix figures with some 1/35 vehicles, maybe.
