Flip it over and look for identification marks on the BB shell.
Research from there. The frame is similar to my '78 Masi gran Crit. frame
On my frame I know size, year it was made, which 1/4 of the year it was made, and production # of said 1/4 year and where it was built(by the year not the #). MC62 C7848 is all mine has stamped on it.
Take a peek and let us know.
