REDUCED- Vintage STORM ALERT PANEL METER, "SFERICS", New Old Stock, Unused, READ

Description

REDUCED! I actually have a small case of these panel meters! Found in a small town estate. I believe these are from either late 1950’s to 60’s. I once owned a "Sferics" Radio that had this exact same Storm Alert meter in it. Cannot find a name on it. The back is stamped "calibrated for steel panel" and an inspectors number. These are new and unused still wrapped in their original boxes. The word "Sferics" stands for Atmospherics. These devices detect the lightning or electricity in the storm and measures the intensity.
You can read the post below.
Anyway, Iike I said, I still have several of these in unused new condition. Why this old guy had these is a mystery to everyone. I like to buy strange, obscure stuff! This listing is for 1 meter as shown. Take a look. Measures 3 3/8" by 3". Ships First Class mail carefully packed. More than one will ship Priority at a slightly higher cost. Examine the pictures as they are part of the description. All questions answered quickly. No returns. Thanks and God bless!
This is the post from 2007 about a Sferics radio someone found:
Oh, I would love to see a schematic to this Texas brand. Sferics is short for Atmospherics. It is a fifties radio. This particular one, according to the papers I have, was bought in Wichita originally. But Rider's, nor Sams published a schematic. In the 60's, the first storm radios that picked up a Weather Bureau warning were made. This radio gets its signal directly from the storm. It works similar as to how you can turn on an antenna-signalled TV, and tune it to channel 2 or 3 or 4 (whichever one doesn't have a station) and turn the brightness down. When the storm produces enough lightning to turn the tube white: head for the storm cellar.
The Sferics radio picks up the static above the broadcast band and makes the needle go up. When it gets into the red, an alarm sounds. I've heard the alarm go off when the sun was shining. But a tornado, or at least a big storm, was in progress within 50 miles.
