Can anyone view the OP's photos? It seems at least one member has seen the Guerc - he points out the finish isn't Chromovelato, but flaking paint.
When I check out the OP's Public Profile, I get this indication: 'You have not added any albums yet'.
Kinda like to see this thing, as I've owned/operated Campy 50th in a prior lifetime. Cleaned up, sold for good money after getting a decade's worth of use.
OP: you likely are sitting on a gold mine. If you make another 6 posts in the next couple days, you'll be able to post pics directly to the thread (and we can help you with that if you have difficulties). Pics will allow those with knowledge to better assist you.
