Guessing a 141T ?

  Good guess, but my date was wrong. It wasn't 1974 it was in the early 90's apparently (8596E btw). I suspect there is a decoder ring for the serial number which would tell me exactly. I've updated the date in my original comment.

    The first two digits of the serial number gives the years since 1960 of the revision for HP.

      Hmm, well then it would be 1999, first two digits are 39.

        i would expect any HP RF test equipment from any age to be fixable and usable (worse case, perhaps new vacuum tubes!)

    Can’t beat 20th century HP test equipment. The pinnacle of quality. I have an 8566B at home. These things are built like tanks, and were made to operate in high temperature environments. We had about 10 of them at work, and the only things that would fail (slowly) are the CRT supplies. I’ll get the LCD retrofit when that happens.

      Have used one of those ! The 'automation' for its time was great. And calibration; signal amplitude measurements were always right on.
