I was being cagey with the exact auction but here it is...

It is a c. 1980s frame/fork by Dutch builder Ko Zieleman. It's the second to appear on eBay recently and from the same seller. This one, despite the ding which was pictured the same way it is here, did 'sell' for over $900 a few weeks ago, a remarkable price. But now it's back. I have emailed the seller to ask what happened, which seems like a fair if perhaps embarrassing question, but have not received a response.
As Elev12K notes, it's unusual for KZ frames to turn up. I'd say especially unusual for one this small, coming from a land of tall people. So perhaps this is the only chance I'd have at one for a long time. But how much of a compromise could I live with in order to have that bike? If it were a bargain price and I could be 100% sure everything else was fine, that's one thing. To pay top price, it had better be perfect.
ps: long as we are on the subject, both Elev12K and Lotek, Zieleman owners themselves, have been very helpful to me in considering this. Thanks guys!
