Sometimes the rivets won't take solder. Scrape both rivets and body. ?Try soldering a again?

I'll try a little solder on the rivets and lugs. From the plug to the first lug is OK. Nothing on the other side, switch is open at the rivet.

And again, another reason to go to Dayton! Bunch of our club members there now but I am still not up for the trip these days.

My very first impression was "If you can't find it at Dayton, then it probably never really existed in the first place!"
