My understanding is that the Asso (ace) term is part of the marque name rather than a model name.

Five models of road machine were offered. The top four all employed the same Columbus tubing frameset.

Your curved QR skewers are a stock Campag item and period plausible for the bicycle. They were sometimes referred to as "track skewers." As you noted, the curve is much sharper than the later Campag curved lever skewers.

Frame construced with Agrati "AM" pattern lugset nr. 000.8040/U. The cutouts are a customization of the stock lug. Pattern also employed by Galmozzi and others. The seat lug was offered in several configurations. One could have it with Malaguti plugs and no binder ears as on your frame. Or it could be ordered with standard binder ears with or without the plugs.

You are most fortunate to get the OEM forged binder collar with the name. These are much nicer than the more commonly encountered stamped collars. They are a Magistroni product as shown by Joel at the blackbirds site:

Only the top one or two models received the Campag headset. Others received the IDEOR - Magistroni set.
