I'm just wondering if someone might be able to tell me if
Gem lids (for crank machines) are interchangeable, i.e., if an
earlier Gem lid will fit, say, a maroon model D?
I have George Frow's "Companion", though I'm still unsure.
Thanks
Ade
Apologies, I think I've answered my own question, thanks to Mr Frow.
p147, it says the cabinet was a little longer than earlier cabinets..
