I have a couple of Jennings vacuum coaxial relays,
Actually those are transfer relays marked 2.5KW@30Mc.
Those are equipped with N-connectors.
I think I saw similar on the SSN webpage.

My old Jennings catalogs show nothing like that. Two things that don't sound
like Jennings, at least from the packaging you described. Jennings used
either a circulator connector for their larger relays, or turret pins for
the small BNC and type N. They didn't have any with SO-239 connectors. Also,
they had two main configs, a box 1.35 x 2.2 x .75 inch with three BNCs on
the narrow side (1.3x0.7),or a box that is more square, with connectors on
three of the narrow sides. Of course it could be a special that they made,
or could be a Jennings inside of a box made by someone else.
Did you find that National R175A choke.
