[Heathkit] WTB knob

[Paul Kraemer]

Merry Christmas to all my friends on Heathkit
I am looking for a dark gray knob from the test equipment of around 1960's, 
the dark gray cabinet.
This knob is what I would call the tuning size for various generators or 
analyzers.
It is almost 1.5" dia X slightly more than 0.75" tall
Has many grooves about the circumferance.
I tried just replacing it with a common off the shelf knob but you know it 
works but just doesn't look right, especially since there are two. Have 
one---need the other.
If you have one you could sell reasonable please contact me.
Thanks and Happy New Year in advance.
