Here is a very nice POSTWAR LIONEL O GAUGE #151 TRACK SIDE SEMAPHORE w/ BOX, CONTACTOR and INSTRUCTION SHEET! It has been gone through, cleaned and serviced. 

It has been tested and works as it should. The light bulb works, the semaphore comes down when a train is on the 145C contactor.

Also included is the original box and insert. But is missing the cellophane which covers the opening.

The instruction sheet and 145C contactor are also included with this sale.
