USA made shifter! One Street Shifter: Store Literally looks like garbage, but it'll shift.

Sounds like there are a few other niche derailleurs that were made around the same time as Paul's.

"While the $280 derailleur was soon joined by similar models from Precision Billet, Prototype Machining, Rhino Racing, Gorilla Billet and White Industries, none possessed the allure of Paul’s masterpiece."

Looks like Precision Billet has been reincarnated! If you expand your requirement to include made in USA and CAN, then you can use these. http://www.precisionbillet.com/home.html
