Hi all......
a newbie here, jumping right in to ask for assistance please. The topics and people here seem to have diverse wisdom. Regarding electronics, I have neither!
I am trying to work with a person who has some very vintage electronic equipment, from a Calibration Lab. This stuff has the dates of 40's and 50's. Still in working condition. It is Calibration Lab quality, never used in general production. With a desire to possibly part with this equipment, what are routes to investigate? I already have inquiries to some of the sites given here, who offer to buy/sell various items. One item in particular is the Sensitive Research Instrument Co., Universal Polyranger.
Let's even try the photo thing on this one. Click image to enlarge.

How about an original Weston Voltmeter or Ammeter, documented 1944?
Does such equipment draw an audience on ebay? There are also museums hosting such equipment. If you had this, what would you do? Again, the question leads to advice concerning such a variety of vinatge equipment. Thanks to any/all who care to respond.
