What are the difference between your ranges - how interchangable are they?
The us figures have the kepi which where the us's main stay head wear, the cs have slouch hats, the cs wore both kepis and slouch hats, they are very interchangable since both north and soth wore both forms of head where but the us wore mainly kepis. ;D
Cheers.
Don't forget to mention the belt buckles and buttons ... US had US stamped on them ... CSA ... well you know the rest.
You're a bad man Major F! :P
And now to crank this anorak into overdrive - they mostly weren't kepis, they were forage caps.
