S Signal Tower S Signal Tower
If you have information on this signal tower, we (Mark Preman / AmericanFlyerTrains.com and myself) would love to here from you.  The heads have two small screws that allow access to the inside.  The socket and plug looks like a tube (as in radio tube) socket. These things are very tough.  Built to take a lick'en. No weathering needed.  The extra head has a clip, but I suspect that it was soldered on at some point.  Mark has more of these available.
