The good news is, there is a Masi frame that I built on eBay this morning and the bidding is only up to $2.25.
Masi frames were numbered A, B, C, and D for the four quarters of the year, followed by the year 81, and 14 was the number frame that quarter. So this was built in the 4th. quarter around October 1981 (Not 1984 as the seller has it listed.)
I built Masi frames from October 1980 until the end of December 1981. On the other side of the bottom bracket is the number SMC59. SMC is for San Marcos, California, the location of the Masi frameshop, and 59cm. is the frame size.
This is the bad news.....
The item number on eBay is 260082503350
It might be worth $2.25 as a conversation piece, but with thirty bucks added for shipping I'm not recommending this one.
