seeking info on Western Microwave mixer



I am seeking information on a Western Microwave MSS-5079A mixer.

This is ancient stuff, guestimate is 1970s. I tore down a Loral Radar Warning Receiver and there is quite some WM stuff in there. Plus Watkins-Johnson YIG GaAs oscillators and preselectors. Unfortunately all this is from before the Dawn of the Internet so search engines prove essentially useless.

Who can help me here please?
