Crank Telephone Appraisal

Antique Wall-Mounted Crank Telephone

This is an antique wall-mounted crank telephone, likely dating from the late 19th to early 20th century, specifically the 1890s to 1910s. The primary material is dark stained wood, possibly oak or walnut, which forms the main rectangular back board and the lower shelf. The wood exhibits a rich, deep brown color with visible grain, suggesting a natural finish that has darkened over time, or a dark stain applied during manufacturing. There is some visible wear and minor surface abrasions consistent with age and use on the wooden surfaces, particularly on the edges of the shelf and the main board, contributing to its authentic patina. The construction appears sturdy, with visible joinery or screws securing various components to the wooden backboard. Key features include two prominent brass bells mounted at the top, which show some tarnish and minor discoloration typical of aged brass but no significant dents or damage. Below the bells, a small rectangular nameplate or instruction plate is visible, though the text is illegible from the image. To the left, a black, possibly bakelite or hard rubber, hand receiver is suspended by a metal and wood hook. The fabric-covered cord connecting the receiver to the main unit appears aged and somewhat frayed in places. Below the nameplate, a central crank mechanism is visible, likely used to generate a signal for the operator, with a visible metal crankshaft and a small, dark crank handle protruding from the right side of the wooden board. At the bottom, a heavy brass or bronze voice transmitter/mouthpiece extends from the wooden shelf, featuring a a cylindrical shape with a flared, dark opening. The craftsmanship appears robust and functional, characteristic of early telecommunication devices. There are no obvious signs of recent repairs, suggesting the components are original. The overall condition appears to be good for its age, showcasing historical significance.
