Retro Guru,
Thanks a lot for your replies. I have found a company which sells replacement chain rings and I'm going to take a chance on one of those. If I come unstuck I'll get back to you. Thanks again.

I'm looking for a 50 tooth chainring for a Shimano SG chainset or a triple chainset with 50 or 48 min teeth square taper for 6 speed chain.
Any help appreciated.
Mike
