Help me identify a coax switch. It is part of an SK estate.

It is a B&W “Soup Can” (sealed) 6 position coax switch, with the connectors on the rear.
It is similar to the Protax line, and while it is marked B&W, it is not marked “Protax”.
It resembles a model 375 or 59.
It does not ground unused ports.

Can anyone shed some light on what I have, so I can list it on the classifieds?

Similar but not the same. I posted links to pictures - front - back and side.

I can't imagine why it would need to be identified any further than it already is. If you're looking for specs, it can undoubtedly handle full legal limit at any reasonable SWR and probably any unreasonable SWR.

It certainly looks like a B&W 375. Perhaps sold before the marketing term Protax came along? Everything I can find on the 375 mentions that it's a shorting switch and you indicate that it's not.

What more do you need to know?

We are Coulomb of Borg. Resistance is futile. Voltage, on the other hand, has potential.

I was hoping to find a definitive Model Number.  I know that these switches are sought by the contest stations in the Caribbean because of the salt air corrosion with which they deal.  The non-shorting is what threw me and convinced me it was NOT a 375. 

Thanks
