Thanks for posting this most interesting find!

Will look forward to additional imagery.

Constructed with Agrati "BRIANZA" lugset. Frame ends likely Agrati as well - they did a dropout which looks identical to Campag Sport, save that it is unmarked. Has the small hole for the spring of a Sport model rear mech.

Rear mech and shift levers not original. Front mech original. Appears to have been originally sold by a shop in Piacenza. One might suspect a nearby manufacturer...
