I finally took delivery of an ARMO M4A2 (75) which I planned to make into a Sherman III and - Lo & Behold - I cannot find the cast British Stowage parts I had purchased on ebay (which is why I was going to make this.)

Does anyone know where I can get the long asymmetrical storage box and the back-of-the-turret box in 1/72? (or 1/76, 20mm, 25mm, resin, metal, anything?)

TIA,
Tim
