[time-nuts] Interesting looking crystal on ebay

[Bob Camp]

Hi

The Sulzer OCXO's were made with a wide variety of crystals. The 2.5 MHz was
one of them, as was the 5 MHz 5th. James Kinghts made a lot of what he
used...

Hi,

I'm guessing that is what a Sulzer oscillator crystal looks like. I 
haven't pulled the crystal out of my Racal MA259 just to see how it 
looks though.

This article refers to the Warner crystal and the Sulzer Oscillator.
