Description

Antique Laboratory Induction Coil. Shipped with USPS Priority Mail.
This is a vintage Laboratory induction coil. It measures approx 10” x 4”. Has a 2 position selector switch. Underside is marked Detroit Coil Company and 3 Volts. Missing one wood screw on underside of base. I applied 3 volts power to the item and it does buzz as designed. An attractive display piece or clean it up and put it back into service. Offer as is.

I am not an expert but believe this is a porcelain-insulated Edison base, dating from pre-1900.
