[Boatanchors] Signal Shifters Again

[Wilson]

OK, I now have three shifters, but not many coils.
Please let me know if you have or know anyone with ham band coils for sale.
And I’d like to get one of the ones with the big external dial and vernier drive, like this:

I’m also interested in finding out when the first model Shifter, the one with the airplane dial, got its first VR tube and when it got its second.
I’ve seen pictures of all three arrangements, so I hope I can find out more.
I’d like to get an example of the very first one, with no VR tubes.
