Still struggling with this one. The only seat cluster I've seen with the same little hole cutout is the one on the Geoffrey Butler (see above), which says nothing about the actual builder anyway since GB didn't build frames. I pulled the fork and there's no stamp there either. Odd copper plating on parts like the dropouts. Maybe chrome wore off and this is intermediate plating?


The fork crown is almost identical to the original Cinelli types but doesn't have raised areas near the brake holes. There's some Holdsworth Fastback Mistrals with the same headlugs, but there's not enough pictures of the seat cluster out there to get a good look. Seatpost measurement suggests Reynolds 531.

Brakes and crank are late 60s/early 70s (no number marking on Strada, etc). But who knows if original.

If I don't find a builder I'm thinking of building it up in the style of a Raleigh Super Tourer (with a made-up make and model tbd).
