Dual bottle bosses and internal brake cable routing started becoming popular circa 1985, so it's probably not older than that. However by this time almost all the big manufacturers and the smaller, prestigious manufacturers were embossing names or logos on the frames. Questions that I'm sure will come up are:

What is the BB shell threading?

Dropout manufacturer and spacing?

Required seat post diameter?

Any markings of the fork steerer tube?

Any ridges inside the bottom of the fork's steerer tube?. If so, are they straight or helical, and how many?

The chain hanger is distinctive but I don't recognize it.
