    Hmm, I see what you mean. It appears to have one too many digits! I'd assume November 1972, based on the info at http://www.waterfordbikes.com/2004/d...nt/sn/over.php

    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!

    T-Mar, if EVERYTHING I knew was half of what you know about just bicycles, I feel that I would be a genius.

    T-Mar and I are still trying to figure out Bianchi's serial numbering system.

    What era Bianchi are you trying to figure out?
    The early '60s Specialissima serials seem to start with 16x.... with the "x" being the year date. I have one starting with 164.... that I'm quite certain is a '64 model. Other than those early '60s #s, I know nothing more about how Bianchi went about it.

    Why does it have too many digits? Looks to me like the 262nd Pmount frame made in November of 1972. That is a high frame count for a month, but this was the bike boom era.

    What you say is a logical assumption. It's just that the Waterford and other Paramount websites indcate that the sequence number was only two digits. This implies that less than 99 framesets were typically manufactured in a month. A jump to at least 262 is a BIG Christmas rush. If there were months where over 100 were prodiced you would think that the websites would indicate that the sequence number was "two or three digits'.

    However, your point does have merit. Prior to 1970, the serial number format was MYxx, where M is month indicator, Y is year indicator and xx is sequence number. In 1970, the fomat was changed to MYYxx, reportedly because of "added capacity for the boom years". Normally, I would associate added capacity with more frames being manufactured, but in the this case the sequence number is still two digits and does not allow for any increase! One would assume that an increase in capacity would have necessitated a three digit sequence number, but the only change to the serial number is to add a digit to the year indicator, so that the decade is included. Hmm, all these websites would appear to be wrong, or at least incomplete. The boom and added capacity should have necessitated a sequence number of up to three digits, unless pre-1970 production had been very small, like 30 frames a month. If a two digit sequence number is correct, then the change in fomat was not to accomodate increased capacity, but to add decade resolution.

    Thanks for that info. Didn't realize that. I've seen that scheme on the early Schwinn Super Sports and Superiors with the forged Huret rear dropouts, but haven't run across it on the Paramounts(I don't see many early Paramounts!).

    While MYxx was the previous format , it was short lived (on Parmounts it was in use from only 1966 to 1969). The short life span undoubtedly contributes to the scarcity of samples.

    Tmar thanks for the info I'll check the campy gear tonight, and if you could keep me updated on your bianchi numbers I'm going to be buying a Bianchi from the 60's or 70's at a local shop.
