I got a choke lever for some sort of 500 falcone off of ebay. it came from the old yugoslavia (serbia?). I'm guessing they have tons of nuovo falcone spares. I was going to use it on my EldoVert with the Chinese/Keihin/Amal replacements, but I'm too lazy to fabricate custom cables, so I continue to use individual choke levers on each carb. At least it looks clean that way.
