Might be an idea for a accessory set - Ammo boxes . rubicon could do a German set , clips and 2 clip boxes for the 20mm flak , as well as metal and wood boxes for the 50mm pak , wood boxes and metal tubes for the 75mm pak , and a variety of wood boxes for the long barrel kwk 75mm of the Panther and the Tiger's 88 . A set of 6 pounder metal boxes as well wooden boxes for the US 75mm , and wood boxes for the Russian 76 , 85 , 122 mm might work as a Allies set . Could also just make them in resin and sell them in 10 piece bubble packs , they do that a lot in 1/35 scale
