Hi All,
A couple of years ago I pulled the 10Mhz reference XTAL out of one of my
freqency counters, in anticipation of replacing it with a more stable OCXO.
The OCXO turned out to be faulty, so the project was shelved. In the mean time
a couple of better counters turned up - so it stayed on the shelf in bits
awaiting a roundtuit.
Today I started reassembling, but could not find the original 10Mhz crystal.
I'm not stuck for one, but I did come across another 10Mhz OCXO which looks
useful except I have failed to find any data on it.
It is marked as follows and I wondered if anyone might have a data sheet or
pin out and voltage spec.?
It was pulled from a cut off section of modern PCB, so post 1975-ish and
likely later than that - I don't know which is the model number, so I've
included all.

5 pins two at one end are to case or ground, the other three are insulated.
Its about 2"h of the PCB x1.5"w x 0.75"
