M.H. Rhodes 15 Minute Timer
This is a M.H. Rhodes, Inc. 15 Minute Timer. This is the company that makes the Mark Time brand of timers. It has a phenolic body and a metal faceplate with plastic knob. It sounds a loud, single chime at the end of the cycle. This is the same timer case that would have an electrical switch unit inside. This particular one just has a spacer where the switch unit would be.
