I'm trying to identify a Hallicrafters AM/SW receiver from, I would guess, the mid-50s. There is no model number, but "MARK 1" is stamped on the top of the chassis. It has five tubes (the standard 35W4, 50C5, 12AV6, 12BA6, 12BE6), four bands (AM and SW covering 1.7 MHz through 30 MHz). There are four knobs (tuning, selector, on-off/volume, and bandspread; three red slide switches; and a large slide-rule dial. I need a manual (or at least a schematic), and a copy would be fine. But first I need your help . . . what is the model number of this thing?!

Hello:

Sounds like you have a Hallicrafters S125 Starquest (1970-72).
The radio was identical to the S120 with the exeption of
the 3 slide switches. Made in Japan for Hallicraters and
one of the last of the Hallicrafters line.

Hope I am right and hope this helps.
