Have a bunch of these and have been unable to find out info on if appropriate for late 1930’s time frame. Want to add as much detail as possible to new layout.
Heres a thread in the Trains forum from 2007, maybe you’ll find some info there.

Mike.
I doubt they were around in the 30’s
They were but what form did they take ?
Interestion, didn’t know about those, but still need the info about the ones attached to the rails.
