Leica R lenses: 1 cam, 2 cam, 3 cam, 3rd cam and ROM - what's the difference?

Great explanation

Will a 2 cam work on a 1 cam? I'm looking for lenses for my mother's old Leicaflex SL. She had several lenses at one point but between moving and downsizing, we can't find any of them. I'm pretty sure it's one of the early models from the 1960's (1 cam version).

SL needs 2 cam lenses

There was an issue for a couple of hours this afternoon. It’s now working again. Thanks for the heads up.
