You are looking at an original Lionel UTC lock on. It can be used with ANY traditional tubular style track. It cannot be used with roadbed style track such as Fastrack. It was offered by Lionel in the prewar era, 1936-42, and then again in the early postwar era. but it can be used with ANY era of O, 027, and Standard Gauge traditional (tubular) style track.
This one is used but CLEAN. Very clean! If you are looking for a CLEAN one, this is the item for you.
It is just what you need to get power to the track from the wires coming from your transformer. This one is vintage, clean, and working.
The neat thing about this one is that it is adjustable to work with ANY tubular track whether 027, O or Standard Gauge, prewar or modern.
CONDITION: C-8. Very clean! if you are looking for a CLEAN one, this is the item for you. Does have a spot of oxidation, but wow--clean! Not often found this clean.
