As well as being sold separately for those of us who have other companies kits in need of detail bits , it might be an idea to include a German Stowage Pack in each German vehicle kit if it doesn't add to much to the cost . Other nations can have theirs added as they are developed . Academy does this in 1/35 scale with all their M3 / M4 US tanks as well as the Panzer IV . Sprue contains spare wheels , track , tools , gas cans packs , ammo boxes , tow cable eyes , etc . Just an idea
