[Hammarlund] HQ-129X Knobs

[Glen Zook]

The "back end" is what is primarily different from the
"garden" variety pointer knobs.  Those on the HQ-129X
are round whereas most of the pointer knobs have a
"squared off" back end.

The two larger knobs are basically the same as were
used on the Hallicrafters S-19R "Sky Buddy" and
similar Hallicrafters receivers of the late 1930s and
early 1940s.  They are definitely not the same as the
"updated" HQ-129X which is better known as the
HQ-140X.  The primary difference between the HQ-129X
and the HQ-140X is that the HQ-140X uses miniature
tubes and the HQ-129X uses octal tubes.  Otherwise,
the circuitry is basically the same.
