A Durkopp track bike with many original parts just sold on eBay for $710. Was the winner someone on the list? I would love to correspond with the new owner. The seller listed it as 1940s bike, but I'm fairly certain that it should be dated in the mid-'30s. It has a head-clip style (Durkopp) headset, a pre-WWII head badge and a 146xxxx serial number, all of which shout '30s to me. The item number is 220347762472.
Another Durkopp track bike has just been listed, complete and original. The seller thinks it's from 1929. I think he's being a little optomistic with an asking price of $10,000. Item number 180323225873.
