[Hallicrafters] Information on S-76 knobs

[K1WGN at aol.com]

Thanks to every one who responded.

Here's what I've discovered.  ARRL handbooks yielded the following:
1950    No S-76 shown.
1951    S-76 shown with no skirts.  W4AWM reported an S-76 with no skirts, 
stamped "RUN 3" inside, S/N D-104651.  Several reported that the S-76 picture 
in "Ostermans" does not show any skirts.
1952    The sensitivity, volume, selectivity, pitch and tone controls are 
shown with skirts, numbered 0 - 9 (or 1 - 10?) except pitch is 5 - 0 - 5 and 
selectivity has a single line functioning as a pointer.  Judging by how close 
they come to the dial housing they seem to be 1-1/2 inches in diameter.
1953    The sensitivity, volume, selectivity and tone controls are shown with 
skirts (pitch has NO skirt).  All have pointer lines.  Again, judging by how 
close they come to the dial housing they seem to be 1-1/2 inches in diameter.
1954    Ditto 1953.
1955    No S-76 shown.

I have two S-76's, both use just pointers on the sensitivity, volume, 
selectivity and tone controls, on one the skirts are 1-3/8 inch diameter, the 
other 1-1/2 inch diameter.  Neither has the pitch control knob with the 1/8 
inch hole so I still need one.  Neither has a "run" number.  (I'm considering 
parting out the unit with 1-1/2 inck skirts.)

It would seem then that there were four variations;

#1.   No skirts    (Osterman's and 1951 ARRL Handbook)
#2.   Numbered skirts including the pitch control  (1952 ARRL Handbook)
#3.   1-3/8 inch pointer skirts, sensitivity, volume, selectivity and tone 
controls only
#4.   1-1/2 inch pointer skirts, sensitivity, volume, selectivity and tone 
controls only
