Hmm, no idea who built it, though the fastback with the pinchbolt integrated is similar to TS Isaac's. I also have seen a few done that way by Glenn Erickson in the early 80s. Both of those worthy builders had the bolt head on the right side of the bike, not the left as in this picture.

Do we know what wheel size it is made for? Certainly something small - 650c or smaller?

Tapering the lug edges into the tubes that way is not pleasing to my eye, and can result in weakening the frame if not done right. Without knowing who built it I'm not sure I'd want to take it on faith that it was done right. Look for any hint of thinning the tubes at the lug edges where they have been feathered in - but the effect may be difficult to detect by eye while still being enough to cause a structural concern. Have it inspected by a good framebuilder if possible.

On the plus side, anyone small enough to ride a 44 with a 46 TT is probably a light rider, and most frames are overbuilt for people this size.
