I can't shed any additional light on this frame but it is very nice. Obviously it is a high quality frame to have campagnolo dropouts. I like the extra braze-ons, the front derailleur cable stop is really cool and I could use one on a few frames. The fork lamp mount is cool and the fork crown reminds me of the early 70's Raleigh competition which is nice. The craftsmanship seems to be nicer than the mass-produced bike boom brands, maybe it's pre 70's?

As much as I like the lug cut outs, they are extremely phallic!
