It's an Ompax...I made inquiries about this one a year ago. It's late 70's, probably Tange Pro by my research and likely made by Kuwahara. Chromed headtube lugs, long Shimano SF dropouts, wraparound stays and sloping fork crown. Comes with a Tange Levin headset and generic seatpost. Semi longpoint lugs. 58cm c-t, 56cm c-c. Nice metallic red over full chrome with one bad scratch on the top tube but it would be a cinch to match. 120mm spread. Almost NOS because I removed the '77 Dura-Ace group from it. Otherwise it's unridden.
This is a very pretty frame, not unlike the best from Miyata, Fuji etc. Pics available
$90 plus shipping...or I'll have to sell it to courier dudes. Make a great fixie. Oh crap...is fixie part of the acceptable lexicon? Will I be flamed?
