Condition: 7 Original Box: 7+ Year: 1949
Here's a clean, all-original 153 Block Signal from the late 1940's. This signal is the earlier variation with screw-in bulbs and the resistor built into the base. The lights have been tested and operate properly and there's a few minor surface marks on the base as seen in the photos above.
Also included are several extras with the signal including; a Middle Classic box with all internal and external flaps, instructions (dated 1949), large packing envelope (dated 1949), CTC lockon, 153C track activator plus the packing envelope for the insulated pins (this one is an empty envelope).
