You are looking at a like new or better 6-24213 lock on that really comes in handy! Use it with your O, 027 or even S! For you S gaugers, it is a cheaper way to get a 690 track terminal.
It is just what you need to get power to the track from the wires coming from your transformer.
The neat thing about this one is that it works with ANY traditional track whether 027, O or S Gauge, prewar or modern. Of course, it does not work with roadbed type track.
CONDITION: C-8 or C-9. Hard to tell if used. Looks like new old stock.
You know that the tubular track is now being discontinued by Lionel, so you have to get it any way you can. Neither is anyone making S scale traditional track lock ons. AND THIS item has LONG been discontined.
