The 1/35th scale open-topped US and German halftrack kits include
interiors of the troop compartments but not the engines. The 1/35th
scale King Tiger with production type (Henschel) turret includes some
interior detail, including the ammunition racks in the turret bustle

Premium Edition Panther D.
Academy has been offering interior detail in many of their kits,

incorrect. They offer fighting compartment interiors in the M3 and M3A1
Stuart kits, as well as their M18 Hellcat and the new M3 Lee.
