Nice looking frame. I have no idea what model it is but I am keenly interested to learn.
FWIW - since the mid 90's Campy gear included Ergo and hasn't undergone wholesale overhauls, I wouldn't hesitate to put a new 10 speed group on it.
I'm not sure I'd put the new Record brakes on it though.
Anyway, nice frame and good luck with the build.
