[Boatanchors] Anyone Seen one of These Before?

[Rod Hogg]

Dave...

The device you have there is a Measurements Corp. crystal
calibrator,Model 111, that was modified by Lampkin Co in Florida and
sold as their -PPM- calibrator for their Model 105 (a)(b) series
frequency meter.  A basic hetrodyne meter.  To make sure the 105 was
"right one" you compared it to the PPM for a -Parts Per Million-
accuracy.

I have one and a manual that could be copied if you need it.
