I picked up a switch just like this one but can't find any info on it. I'm assuming it's earlier than the stamped handle type AC-7, but do not know what year they switched (got to love the puns!).
Does anyone know which switched were in the pre war cubs and early L4s?
Anyone who can provide any information on it, or suggest a place I can research it, would be greatly appreciated.
Thank for you help,
Ed
