Bulley--supposedly the frames for sale from the Ukraine last year were recently-built counterfeits. That was one reason they were offered without front forks--the forks were originally forged and the 17mm tubes added on, specially for the USSR team bikes. It's no big deal to produce replica lugged steel frames, even in one's garage or basement, but forging a custom fork is another matter. The handlebar stem was another custom part, and if a frame doesn't have it, it's possibly a fake.
These counterfeits were offered painted, with the wrong decals applied. The decals were vinyl on the counterfeits. On the original 1980 frames they were a mix of printed pressure-sensitive transparent Mylar and water transfer. There were no non-manufacturer decals (i.e., sponsor or component logos) on the original TT bikes, either, save one on the seat tube for Columbus tubing.
Are your dropouts stamped with the "Colnago" lettering? If not, it's cause for concern. The 8 team bikes all had "Colnago" dropouts. The other 16 bikes that were made for training supposedly all had serial numbers stamped on either bottom bracket shell or inside of one chain stay. The 8 team bikes had no numbers and were distinguished from one another by their water bottle colors! Decal placement on each head tube was slightly different, too.
Though the groupset was 90% Super Record ($$$), there was no pantographing to keep costs and delivery times down.
Here are some photos of my own 1980 TT frame, which came to me with decals intact though very badly scratched, complete headset and custom-forged 3ttt handlebar stem, Record bottom bracket, and forged front fork.
The original photos of my unrestored frame show that these frames had a lot of use once their Olympic Gold celebrity was over--they continued to be used by the USSR cycling team for practice.
Here's the bike, 95% finished, sans cables and decals, which are being made up. With the exception of the original Record bottom bracket, the entire group set is vintage NOS Super Record. Wheels are Nisi polished aluminum, Handlebars Cinelli. Seat post has been turned down to 24mm from an NOS very rare 25mm item. Tires were originally Clements, but are now Vittoria Kevlars because I want to ride it. 700C rear, 650C front.
I'll be riding it a bit soon!
