Hello Everyone,

So I just picked up a used Nishiki Olympic 12 and I was trying to decode the serial number to figure out the year. From what I have been seeing it seems to be a very unusual serial number, I was wondering if anyone may be able to help me out with it. The serial number is located on the underside of the bottom bracket and reads S011F347.

Suntour VX front and rear derailure
Champion stamped on the handle bars
Dia Compe breaks
Cotterless cranks
Chromed tips on the fork
Chromally frame
Araya rims
Yellow paint sceem, with brown decals, and yellow grip tape (I think its original)

It says made in Japan on most of the components and on the frame as well.

Any ideas on the year?

Thanks!
