I was given what I believe is a 1982 Santana this week by the original owners who purchased it new in 1983. I started a thread in Classic and Vintage, and also a new page on my website. More pictures are located in these two places.
The reason for presuming it is a 1982 is the use of Ishiwata tandem tubing. From what I've read, Santana switched to Columbus tubing in 1983.
Today I located what I believe to be the serial number on the rear bottom bracket shell. Does anyone know if the serial number conveys any information such as date of manufacture or anything else? The number is "SE954."
Any help is appreciated! Thanks!
