I'm currently building Trumpy's BS-3 100mm gun that I want to use in a spring 1945 Lake Balaton/Operation Frühlingserwachen diorama. Since I'm not a huge fan of vinyl tires, I would prefer to replace them with resin wheels but the only ones avalable are these: http://www.perthmilitarymodelling.com/reviews/vehicles/hussar/hussar35034.htm
Unfortunately, only postwar BS-3s seem to have these wheels (with only two lightening holes and the offroad tires) - all the WWII examples that I've found photos for have four holes and different tires, just like the ones in the kit:




Does anyone know anything about or has anyone seen photos of a wartime BS-3 with the wheels with two holes and offroad tires? Any assistance would be greatly appreciated.
