[Boatanchors] Updated FS

[RAY FRIESS]

I will likely gut it and use the metal case for something.  It has a handle on it and could be a good grab n go container for an emergency rig.

Ray:

I did not read the responses to your ad. I had a lot of experience with
Wheatstone Bridges back in 1952/1953. In that era Long Distance
Telephone Companies still had a lot of their circuits and carriers on
open wire facilities. As you can imagine, open wire facilities were
prone to all types of failures. Pairs of wires going crossed and pairs
going open. Wheatstone Bridges were a tool of considerable resistance
accuracy. They were used to locate open wire faults. The most simple was
to measure, in ohms, the resistance to the cross. They knew the
resistance in ohms per pole, then a record what pole number would equate
to the fault. Locating "Open" pairs was more difficult. A feature of the
wheatstone Bridge to locate open pairs was a Varley. Varley feature
could be used also to locate "Side Crosses" between pairs. Wheatstone
Bridges were large, accurate Ohm Meters. There were some uses in
industry but I am not familiar with those.

Today, I would say that wheatstone Bridges are absolutely worthless
except an antique or a Boatanchor.
One last chance may be one the telephone companies museum.
Sorry to deliver such dark response.
