Rare 1885-1899 American Bell AT&T Operator Breastplate Headset #234 For Sale

Rare antique telephone operator’s breastplate transmitter with connected single-ear head receiver and double-wire headband.

The breastplate transmitter is marked:

“PROPERTY OF THE AMERICAN BELL TELEPHONE CO.”

It is also stamped “234,” believed to be an individual property or inventory number rather than a confirmed model number.

The connected receiver is engraved:

“PROPERTY OF AMERICAN TELEPHONE & TELEGRAPH CO.”

American Telephone & Telegraph was established in 1885 as American Bell’s long-distance subsidiary. American Bell continued operating until its assets were transferred to AT&T at the end of 1899. The presence of both company markings indicates that this Bell System operator’s assembly most likely dates from approximately 1885–1899, possibly for switchboard or long-distance service.

The contoured breastplate was suspended against the operator’s chest, positioning the curved speaking horn near the mouth. The single-ear receiver was supported by the double-wire metal headband, leaving both hands free to operate a telephone switchboard.

The transmitter and receiver are electrically connected and remain together with their old cloth-covered wiring and two terminal clips. The receiver has the thin “watchcase” construction used on early headband-mounted operator receivers.

CONDITION:

Unrestored antique condition with age-related wear throughout. The breastplate and transmitter show finish loss, scratches and surface wear. The cloth-covered cords have discoloration, fraying and deterioration. The headband, wiring hardware and terminal clips show oxidation and corrosion.

The set has not been electrically tested and is being sold as an untested historical collectible. No guarantee is made that it presently operates.

Nothing has been polished, repainted or restored. Please examine all photographs carefully for the exact condition, markings and components included.

An unusual surviving piece of late-19th-century American Bell and early AT&T telephone history.

Sold exactly as pictured.
