You are viewing a vintage Columbia Electric Mfg. Co. Tong Test AC Ammeter set in the original case. This 6 piece set includes the case, ammeter base assembly and 4 different range ammeter heads. The instruction sheet / manual is included. This gives you the following ranges:
0 to 75A
0 to 200A
0 to 500A
0 to 1000A
This was made in Cleveland, Ohio when the USA was the manufacturing center of the world. This worked when last used MANY years ago and appears to work now when tested. Calibration was not checked though. The back shows one small damaged spot in the frame that looks like a user once had an arcing issue. The case is solid with functional hinges and latches but is scraped up a good bit.
This is great for display and still works to boot.
