I'm just doing some research before I splurge. I bought a bike in November and December now.
So I'm concerned that I'm losing control!
The thing is, the bike of interest, is not NJS stamped. The term used is "pre-NJS".
So would you know when NJS-stamping of components was introduced?
1957 See the article below:

As far as value, to some, a bike that has been raced in Keirin would be special and to others it is simply used! If you are one of the former, then you still want it to fit and for it to be in good shape, frame straight, no major dents, etc. Some are likely abused while others might look close to brand-new. Sometimes hard to tell from photos. Some of the frame manufacturers of track bikes like Panasonic, produce some remarkable product. I'm sure there are bottom-feeders too.
Can you share what they're asking? How did they acquire the bike? All good to know.
As Veganbikes said, track frames aren't necessarily comfortable for general road riding. If that is the riding you wish to do, you might be better off with an All City Big Block or a Wabi. They are still track bikes, but they ride well on the streets.
