Thank you for contacting Mearto with your appraisal inquiry. Based on the photographs and information provided, the subject of this appraisal is a Hammond Synchronous Electric Alarm Clock circa 1930s. The photos indicate that the piece has seen considerable use with scuffing on the crystal, spotting and yellowing on the clock face with a bent second hand, possible paint overspray or mildew spots on the rear of the mahogany case, and repair to the electric cord. Based on confirmed prior sales of similar items at online auctions, its fair market value as-is is estimated at $10 to $20 USD, most likely as a parts piece for this maker, who only produced electric clocks between 1928 and 1941.
