OT: Old high school physics lab meters

Hmmmm...I would not call it huge. In the old radio collector world, the old lab type test equipment is almost at the bottom of the popularity pile. At the old radio swapfests, test equipment, especially the lab type stuff, often ends up in the junker auctions at the end of the day. Sometimes a very good piece can fetch a good price on Ebay, but quite a few more generally do not do very well. There is some good stuff. Any pieces that can be dated to before the turn of the century are good (patent dates are not a great way to figure this out). Any meters with cast metal cases (generally used in power switchboards) are also good. Additionally, any sets that are in super clean condition can fetch a good buck - but I really mean factory-new condition. The meters themselves have value - but only certain ones that are marked with their actual full scale. AC voltmeters from 5 to 10 Volts, as well as from 150 to 600 Volts. DC voltmeters above 300 Volts. DC current meters from 25 to 500 microamps, and from 25 to 500 milliamps. RF ammeters are good no matter what range. Round is better than square. White face is better than black face. Weston is the favorite brand, followed by Western Electric, Westinghouse, GE, Triplett, Roller Smith, Burlington. Null meters are not popular. -- Will
