Well, you should be able to corroborate this using components date codes, providing the components are original. Campagnolo Record hubs were standard and the backside of the locknuts will be stamped with the last two digits of the year of manufacture. If it's a road racing Parmount then the Nuovo Record rear derailleur will have a Patent date, stamped next to cable housing recess, that indicates the year of manufacture. Campagnolo normally stamps the backside of the crankarms too, but this practice started in 1973, so yours should have no date codes. The crankarm code for the 1970s consisted of a diamond with a single number that represented the last digit of the year of manufacture.

If the crankarms have no date code and the hubs and derailleurs indicate 1972, then you should have a high degree of confidence in the frame being November 1972. Even if one of the codes were 1971, I wouldn't be suspicious. Good luck!
