Many thanks to the CR community for helping identify my mystery track bike. It seems pretty likely to be a pre-WWII Durkopp. It has clearly been around the world, since when I acquired it the components were Italian (Cinelli steel stem & bars, Campy headset), Spanish (Zeus seatpost), British (Bayliss Wiley BB cups) and French (TA Criterium crankset and spindle). I compounded the mix by adding a Japanese brake lever to control a Campy front brake for road riding.
Now comes the fun/hard part, as most of you have enjoyed/feared: restoration. Last night I had dreams of dancing Scheeren rims (just out of reach, of course). And maybe those are the easiest parts to find!? I've never looked for pre-WWII German parts before, so I'm hoping that you all will help me out here, at least with suggestions and leads.
One of the first things I will do is have the powder coating removed and the dents and dings on the frame cleaned up in anticipation of a super re-paint. I know that some of you out there do this for a living. Am I better off in your hands or can an attentive amateur undertake this sort of project one step at a time?
Of course, I could instead make it my goal to have a veritable United Nations result - the most varied (by country of origin) track bike on the planet. Maybe an Avocet seat and some Russian wheels?
