I bought this Kiron 70-210mm f4.5 MC lens (@55mm) on Ebay and it was advertised as an OM Olympus Mount. So I bought a OM - EOS adapter for my Canon 600D and it doesn't fit? Does anyone recognise this mount? Thanks?

That is "Canon FD" mount for sure.. Really looks like.
I use FD zoom with macro too, by Tokina, with lensless adapter.

Is it worth getting an adapter, gonna lose another stop of light with this one? I have a Canon 600D.

FD is one of the few common mounts that has a shorter registration distance than Canon EF, so if you could find an adaptor you would not get infinity focus without additional optics. There are many good zooms in this range that would be more suitable (mounts such as nikon, minolta, M42, Pentax etc) and won't cost much. This lens would be better on a mirrorless (sony NEX or micro 4/3)

If you buy an adapter anyway, get one without glass.
You can't focus to infinity but that imho still much better than massive IQ decrease by crap optics inside infinity corrected adapters.

Cool! I didn't realise that they came without glass, I thought all the FD adapters had glass, not gonna need infinity much with a long zoom anyway!

If you were buying it for its close-up properties, the extra flange distance will give you a bit extra close focus (not as much as you would get with a wide angle lens though)

My Tokina 35-105 with that adapter(I bough with glass, but remove it after a few weeks), can focus only on 1-1.5 meters in 105mm set. But in "macro" mode it works great. )
