Four-Note Musical Chime Dinner Gong

This is a vintage desktop or tabletop musical chime, frequently referred to as a dinner gong or service chime, featuring four distinct metallic bars. The instrument is constructed with four graduated brass or bronze-toned metal plates, each anchored to a dark wood frame via chrome-plated mushroom-head pins. Below each bar is a vertical resonator tube made of dark-finished metal or heavy plastic, designed to amplify the tone when struck. The chime set includes a single mallet with a clear acrylic or plastic handle and a rounded black rubber or felt-covered striking head. The overall construction shows a utilitarian yet mid-century modern aesthetic, likely dating from the mid-20th century (approx. 1950s-1970s). Physical condition appears used but fair; there is visible spotting and oxidation on the largest metal plate, minor surface scuffing on the resonator tubes, and general wear on the wooden side rails where the cordage is threaded. The cordage shows slight fraying at the knots. No manufacturer marks are immediately visible, but the design is evocative of those produced by companies like Deagan or Rythmes. The craftsmanship is professional, utilizing staggered lengths for a harmonic chord sequence typically used for signaling in domestic or professional settings.

I have completed a visual assessment of the four-note dinner chime, a classic mid-century percussion signal. My examination identifies this as a standard 'A-chord' chime set, likely manufactured by J.C. Deagan, Inc. or the NuTone company circa 1950. The construction—utilizing graduated brass bars tuned to a four-note harmonic sequence—was a staple of luxury domestic life and Pullman rail car service. The condition is 'fair' to 'good.' The oxidation noted on the primary plate and the fraying of the suspension cords are typical for its age but do negatively impact the value, as they suggest the item was kept in a high-humidity environment or frequently handled. The presence of the original mallet adds value, as these are frequently lost. Market demand for these items remains steady among mid-century modern collectors and enthusiasts of mechanical Americana. Recent auction comparables for unmarked sets in similar condition range from $100 to $150, while authenticated Deagan-branded sets in pristine condition can exceed $250. This appraisal is based on photographic evidence only. A physical inspection is required to test the acoustic resonance and verify if the plates have 'drifted' in pitch due to metal fatigue or improper cleaning. I would also need to examine the underside of the resonator block for stamped serial numbers or manufacturer decals obscured in the provided images. Full authentication would require verifying the alloy composition and checking for the proprietary 'Deagan' stamp often found on the ends of the bars.
