Need help identifying an exotic UHF connector or adaptor...

We just bought out an entire electronic surplus house and are having trouble identifying certain parts.

This one is an obviously expensive UHF to something adaptor or connector.

The sort of stuff that Amphenol is good at. But no id or markings of any kind. Heavy chrome-looking plating.

Picture an ordinary UHF 50 Ohm load, except no resistor and a pry-off plastic cap. The inside end of the male pin is screwdriver slotted.

The pin rotates with physical resistance but does not have a screw or threads or any other hardware associated with it.

Coming out the side is what looks like a 5/16 od x 1/2 inch long internally threaded shaft spacer.

The threads may or may not be real threads (crimp retention?), and they clearly just miss being either SMA or 1/4-20 compatible.

The slot on the male pin aligns with the center of the spacer.

Everything else is otherwise empty.

What is it and why? Value? Demand?

Maybe a right angle connector ? Either the dubious kind that threads onto the coax braid directly, or missing a piece that threads into the bit sticking out the side. Solder inner conductor into the centre pin slot. Does that make sense ?

It's an RG-59 quick connect to 50 Ohm RF. It allows one to use the wrong size coax for a job meant typically for a bigger feed.

You screw it onto an RG-59 coax with the sheath removed (some) and the ground shield folded back over the remaining sheath. That is what the threads grab. There should be a needle shaped center jab conductor in there as well, and that digs up into the center wire on the coax. Solderless, and debatable as to reliability for anything other then receiving.

At least it looks like the right size for RG-59.

PL259 connectors serve as a good education that, in practice, you often can get away with an awful lot of impedance bumps -- people who get a formal education before playing with this sort of thing often get way too hung up on any and all such bumps... and VSWR, for that matter! :-)

It looks like one of those horrible PL259/SO239 compatible things which aren't really impedance matched to anything in particular. They're probably ok for use up to a few tens of MHz, or for connecting up antennas which are themselves already in need of a matching network. You might be able to sell it to a CB radio enthusiast or a less discerning radio amateur who doesn't yet know about N connectors.
