I bought this used F back around 1976, to replace my previous F that I had hosed. It had the winder and self-timer lever from the F2, unlike a typical F:

I don't remember where I bought this, perhaps Olden Camera in Manhattan. Anyway I've always been curious why it had these levers. Anyone know? Thanks.
