I bought a couple more O22 switches yesterday, and, while working on them, I got to thinking about all the variations of these that I’ve seen. I’ve never seen any sort of list of when the different variations of these were made, and wonder if any of you could point me to one(if such a list exists).
Anyway, here’s what I’ve seen
Baseplate screws:
1.Three hex headed screws, two on either side of the divering route, and one one the outer edge of the through route
2.Three flat-headed screws in the same arrangment as above
3.Two flat headed screws, one on the outer edge of the through route, the other in the center of the diverging route
Baseplate:
1.Paper liner under the baseplate
2.No paper liner under the baseplate
Name plate:
- Large sans-serif Lionel and all other words
- Bold Lionel with serifs, all other letters sans-serif, smaller, and darker than previous plate
Lamp Socket
- Bayonet socket
- Miniature screw socket(before 1950, I know)
711-216 Bracket
1.Black painted steel
2.Aluminum
Rail Mounting
- Aluminum “spacers” under the bent tabs on some rails
- No aluminum spacers, some tabs missing for easier assembly.
Most of the features overlap.
Any help would be appreciated.
