I have a frame built for Mick Walker Cycles of Skipton Yorkshire, The frame was supplied by Mel Bentley of Leeds Yorkshire. Mel Bentley was not a frame builder so who would have supplied frame to him from say 1975/85 the frame has the number 904 stamped on the bottom bracket is 531c reynolds tubing with slightly decorative Luggs
any ideas would be of assistance as I am refurbishing it and would like to get the right name on the frame. Thanks

PICTURE please. Roger

Frame being Resprayed will post pictures then and now when I get it back

Offhand, I have no idea but I can tell you to eliminate the early portion of your timeframe. Reynolds 531C made its debut circa 1983/1984.
