Here is a Gargraves three rail switch. It appears to me to be a wide radius as the left hand rail is very gradual...? I do not know fior sure as the box is not stamped, but based on the measurements, I would say it is #145, 072.
The straight part of the switch is about 14.5" long.
The left hand turn off of the switch is more like 15.25".
The frog works.
It has the Phantom middle rail (blackened).
With four track "pins".
With the original instructions.
CONDITION: Appears like new or perhaps new with some oxidation from sitting.Generally shiny rails. Manual frog moves. No motor is included. Box shows significant shelfwear such as softness, etc.
