Engine Order Telegraph Receiver, likely from an engine room, mounted on a mahogany plaque.
The receiver is polished brass, and glass covers a painted face. The face appears to have been repainted, and some of this paint has faded. The face is labeled Pierrot, but research has yielded no information about this company.
