An early 20th-century Omnigraph Morse code training transmitter mounted on a finished wooden base, manufactured by the Omnigraph Manufacturing Company of New York, N.Y. Designed as an instructional telegraphy device, it features a hand-cranked notched letter disc engineered to auto-generate Morse code character combinations, paired with a Brach telegraph key, sounder coils, and brass terminal posts. The unit presents in solid, original condition with expected signs of age and use, including surface dust accumulation, tarnishing and patina across the brass and iron hardware, minor rubbing and finish loss to the central disc's printed lettering, and a small area of wood chipping on the underside near a mounting screw hole; H 3", W 10.5", D 5.5". Please see photos for condition.
