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

[David Knepper]

Mac, several months ago, the CRA was promoting the weighted spinner knob as
"one fits all."  We were wrong.  Careful examination showed that the 51S-1
mounting hub did not allow the "standard" weighted spinner knob from a
KWM-2, for example, retrofit ont he 51S-1.  Therefore, Advanced Optics Ltd.
machined their knob to fit the 51S-1 and the KWM-2.  One knob fits both
models.

Incidentally, this weighted spinner knob, which has been sold extensively to
Collins owners, does not contain buckshot but rather is a one piece machined
knob.

Try one  - you will find that it is an excellent Collins reproduction.
