A quick search found this.

"Canon FL-mount 200mm f/3.5 Telephoto lens

Intensely effective telephoto effects are possible even when hand-held. This lens has a built-in type lens hood and a completely automatic diaphragm mechanism. Compensations for the various aberrations are excellent, and the high contrast and superior resolving power of the lens are its other outstanding features.

This lens is widely used for shooting sporting events, animal life and for news photography besides snapshots and portraiture.

Thanks very much

I had looked at the fl lenses but couldn't see any with the 'M' so I thought it might be something else...

It is something else.

It's not the FL 200/3.5 lens. As you can see in the picture below that lens has no "M" on the name ring:

I would have to see the rest of the lens pictured in your post to be sure but the Canon "M" 200/3.5 is for Canon rangefinder cameras equipped with the reflex housing (aka "Mirror Box.") It is very rare.
