There was a Masi on ebay that sold recently and I was wondering about the serial number. I email the seller and he sent me the numbers as: A7827A MC61. The description listed the bike as a 59cm frame and a 1976 built bike. The serial number indicates a 61cm frame and a 1978 build date. I was wondering about the "A" at the end of the number, any ideas? I decided not to bid because the size was too large and the dates didn't match.
