This is one of the vehicles based on captured French equipment, used by the 21st Panzer in Normandy in 1944. This particular on was a 105mm self-propelled gun, based on the chassis of a Hotchkiss H-39 tank.
I put in a couple of crewmen that I dragged out of PSC plastic 15mm late-war German infantry.
