antique electrical component enclosed in a dovetail-joined wooden box and filled with old black tar/resin potting material. Two cloth-covered wires emerge from the sides, and the front has rusty hardware/terminals. Exact function is unknown—likely an early transformer, ballast, capacitor, or other potted electrical device from the early 1900s to mid-century. Please review all photos carefully—they are part of the description.
