Does anyone know for what year this lamp switch cover/strap was done?
It might be paper or old leather and is attached with screws with washers.
Under, the light copper contact was still riveted on, the far rivet seemed to also have solder on it. The base has all three lamp sockets.
I attached a normal picture -with the light switch stem.
The picture with-out stem has the modification. It had a period black and golden speedo in it, that has 104474 with 509DTN9 stamped (if that helps)
