Ps. Got a PM from someone, though unable to read as I've less than 10 posts FWIW. Thx.

Thanks for that information, Jacob, I always like to keep records on the details of my bikes. Here is my 'interim' build. My original plan was to loot an 8 speed Chorus groupset with Shamal wheels from my De Rosa for this, but I couldn't bring myself to do it. So I've kept the 180mm DA cranks that Mike had, added some DA dual pivot brakes and 10speed 105 brifters and derailleurs, along with the somewhat ghetto wheels. If and when a period correct parts group comes along, I will rebuild.

Update: finally got out yesterday for a test ride, and I can confirm what previous owners have said, very racy geometry, but stable and the ergos fit me perfectly, great bike.
