Front brake appears to be a Reslion "Anchor" model.
The saddle can be saved if you want to have someone recover the cover.
Fantastic RHM. I don't know why I thought of Resilion when I saw Craig's photo - I've never seen a Resilion brake in the flesh - but might have seen your photos before? Thanks for posting. Any idea what time period those brakes were produced?
Guess you might be right about the saddle too - although there's a bit of rust to deal with first!
Also, for general info - the serial number UU909 is stamped on the LEFT rear drop out - if that makes any difference to anyone who knows?
