Thanks for the info, just the kind of details I was looking for!

My hubs are the "no Record" type which might suggest 1963 is very possible, but then I just pulled off one of the front locknuts and it's CAM 60.

The QR levers have a radical, almost 90-degree bend that looks "factory". Those and the shift levers are "closed C".

Headset locknut has Campagnolo Italy Patent, and the top race has Campagnolo Brev Italy. No spring hole in the dropout/hanger.

I had trouble measuring the headtube angle because of the badge rivets, and I suspect it is perhaps slacker than the 72.5 degrees that I eyeballed and that I measured over the badge screws.

I'm wondering if this is the Asso model, which I believe was their top model. I think that the woman who sold me the bike got all of her info from the web, and she was in communication with someone on a forum who likely told her that the bike was only worth a couple of hundred bucks, about what I offered. Sale included almost new Speedplay pedals and a pair of C-Record style pedals with rare ICS clips and Campagnolo straps.
