[Boatanchors] Mackay Master Oscillator wanted

[Ed, k1ggi]

While Mackay marine eqpt is being discussed on the list, permit me to
refresh my search for a Master Oscillator MR-513-7C.

It is an optional unit of MRU-20B console, perhaps others.

At the WCC museum in Massachusetts, we have a MRU-19A/19B console which is
similar to the -20 versions.

Giving it some frequency agility with an original Mackay oscillator would be
a worthy addition.

If any ex-Mackay folks can help or maybe light a fire under an old colleague
or two, it certainly would be appreciated.
