Anyone care to have a stab at the identity of this 50's road/path? Came to me via HilaryStone who described it as having "Mercian-like features" which it kinda does, but nothing uniquely so.
The ridged/double-fluted seatstay caps crop up on mid 50's Mercs but are also a Holdsworth catalogue option c.57-58, amongst other examples. I'm yet to see a good match for the fork crown though, which is a bit plain by Mercian standards, and the horizontal brake bridge would tend to rule out the Holdsworth-family.
Frame presumably 531, lugs Nervex Super Legere. Looks to have been originally black, but there's no trace of original decals.
The complete lack of a frame number makes me suspect it's destined to remain a mystery, but I'd love to be proved otherwise...
