For a while I had a batch of old prewar Lionel switches (from an estate) but I sold them off because I was already overloaded with projects. I remember we had some green switches like this stored in the basement when I was a kid but we were only running HO trains at the time.
The thing that I wonder about is the deep center rail gaps through the switch. Would they snag some center-rail pickups? I didn't get around to fixing up any of these to try them out. I have enough postwar track in operation to keep me busy. But these prewar switches have a definite vintage character.
I did keep a batch of Standard Gauge track with four manual switches. If I ever get around to restoring them! I don't have any Standard Gauge trains (yet?).
