One of the many conversions of French vehicles, this one was (I think) designated LeFH-18 auf GW B2. It was basically a 105mm howitzer in a hexagonal steel box on top of a Char B1(bis) chassis, with a few other adjustments like the removal of the hull 75mm and improvements to the driver's sight.
I was going to add some crewmen to this 15mm 3d print, but there's just not room for them in the fighting compartment, so it can go without.
These conversions started out being painted overall panzergrau, then went to overall dunkelgelb. I don't know if there's any direct photographic evidence of them being painted in the three-colour scheme, but I think it likely, and besides, I like it better.
