Gosh, 20? Years ago there was a bike shop in San Pedro that had a Kvale frame set for sale on consignment I think, $950. NOS, My size close enough, was white….did not really want a white bike.
that shop then moved to OC.
( and I own two white bikes, and still really do not like the extra upkeep )
the appearance of the frame was very clean and tidy, restrained graphics, like an early 1970’s DeRosa.
time marches on.

The blind hole is an interesting detail. When I want to move the axle back I just buy shorter fasteners and springs to keep the protrusion aft short.
