What's compatible with this lens?

My friend recently acquired a Canon zoom lens (FL 100-200 f 5.6 ) and gave it to me as a present.

It doesn't fit any cameras I have currently. But I was wondering what cameras/models the lens is compatible with.

Canon FD manual cameras including the Canon F1, A1, AE-1. Looks like a breech mount type which was later replaced by the bayonet style later on.
