[Spits] Old Spitfire windshields??

[Clark W. Nicholls]

Great! Perhaps we can find a new life for one of my collection!

I suspect most if not all of my empty cases are from early 3-synchro
trannys.

Is there any difference for the 4-synchro 3-rail boxes from 1972?

Is there a stamped tranny sequence number to check for?
