Rubicon - some suggestions for inclusion in the following in your planned Allied stowage set (which, I hope, will include Soviet stuff):
- spare wheels and spare track for M4-type suspension
- spare wheels and spare track for T-34-type suspension
- unditching log for addition to Soviet tanks
- chunkier, more detailed .50 cal and .30 cal machine guns (preferably with a separate handgrip for the .50 cal)
- British 'blanket box' (standard issue stowage box attached to turret of Shermans and Cromwells - there were a couple of different designs)
- spare ammo boxes (including metal 6 pdr and 25 pdr boxes, and wooden crate for Soviet 76.2mm ammo)
- infantry telephone box (often attached to the rear of British and American tanks later in the war)
- fuel cans (both Allied 'jerryican' and earlier British 'flimsy')
- small oil drum (often seen on Allied tanks)
- plus the usual soft stowage
