so...
I recently picked up this bike and was hoping someone on here could help me figure out the frame's age. The thing rides great, SR seat post, elina super pro seat, MKS pedals, Shimano 600 cranks. Feel free to rip on me for the MTB bars and strapless pedal clips. Serial number is KS327810. I will get some higher def shots of lug work, brazes, and decals. any advice?

If that SR seatpost is original it will have a date on it below the minimum insertion line.

The old style font for the logo indicates circa 1973-1975. Unless some of those components are original and the date codes fall into this timeframe, that is about as close as you will get.

You can try http://www.vintage-trek.com/component_dates.htm for dating the cranks, as 600 did debut in 1975, but during this period Nishiki typically spec'd Sugino on their better models, so I suspect these may be replacements.
