Fw: [Collins] 51S-1...dial drag or no?

[David Knepper]

Go to http://www.advanced-optics.com/collins.htm and then scan down until
you see the knob.  Advanced Optics on their second batch engineered the knob
to fit both the 51S-1 and KWM-2 after it was pointed out to us by someone
who bought the earlier knob for his 51S-1.

I have both knobs originally available through Collins and they are
different.
