Dave, if you download the service manual for the EIP Microwave model 545A 
counter, you'll have all the connections and the specs as well.  The OSC 
49-38B oscillator has an alternate part number of 2030010-03, and is used in 
the EIP 545A counter as a time base option.

It's about a 47 Mb download, so if you're on dialup, let me know and I'll 
extract the details for you.
Happy downloading!
