Early wall-mounted crank telephone

This appears to be an early wall-mounted manual telephone set, likely a magneto/crank-style instrument or a related wall telephone assembly from the Chicago Telephone Supply Company (later known as Kellogg). The piece features a wooden wall board with a shelf, two metal bell gongs at the top, a central mouthpiece/transmitter opening, and a separate handset or receiver mounted on the left side. The overall design is characteristic of early rural or business telephones before standardized desk sets became common. The label is an important identifying feature and suggests American manufacture. The handset and cord appear period-appropriate, though the exact completeness of the set cannot be confirmed from the image alone.

Early wall telephones are significant artifacts of the transition from operator-assisted local exchange systems to more standardized telephone equipment. Chicago Telephone Supply Company was an important American telecommunications manufacturer, and surviving examples help document early 20th-century communication technology.
