Boley vs Roco

 

Roco M36 HO scale.  Probably 55 year old model.

Boley M36 in HO scale.  Probably a 10 year old model.

They are nearly identical in most details.

The Boley has various helmets, packs, and gas cans added to the vehicle body.

Here is the Roco turret on the Boley body, fits pretty well, but the hole in the hull is a bit shallow.
