My old Marin Eldridge Grade's serial number is W63DA0009. Doesn't really seem to match up with the decoding formula:
W = ? factory
6 = Muirwoods??
3 = 1993?
0 could be O = ? inches
I do know that the frame was a warranty replacement for the previous owner, perhaps the W has something to do with this? However, I bought the bike second hand early-mid 1992, so it couldn't be a 1993 frame. I suspect it may even have been a 1991 frame. It definitely has the afterburners. The frame is 15.5" so I don't know how this stacks up with O. It looks just like a 0, but I guess it could be an O.
Haven't used the bike in over 10 years, but it is still a really lightweight unit compared to my newer alloy bike.
Do you have any pictures, no idea and the 0 there is not uncommon, no idea on the rest sorry
Do you have an email address for either of those, i'm trying to find the year of my Team Titanium, serial No 4313 but not much luck.
No but I assume
(helps if I spell it right)
or if Sandvik made them them.
I'm not good with the Ti stuff, cost to much for me so I don't bother with the interest or research.
