American best Bell Telephone Co. Receiver w/Working Internal Receiver Capsule

We are selling an early 1900s American Bell Telephone Company receiver w/working internal receiver capsule. This receiver has been fully tested and found to work great. The internal capsule appears to be from a Western Electric Trimline phone. It fits perfectly and works great. This receiver has a place that allows it to hang from a switch-hook arm. best It also has 3 holes in the bottom where the wires would run. On the side of the Bakelite cap, it reads, “PROPERTY OF THE AMERICAN BELL TELEPHONE CO.”-Not legible from the pictures.
