I need a locking nut for my Spectrum FX

I'm lucky enough to have purchased a Spectrum FX, in great condition for $40.  However, the locking nut is completely missing.  Any suggestions Where I can find a replacement?  thank

It's not a locking nut but a behind-the-nut stringlock.... and they are, literally, irreplaceable as an original part.
Westone as a Matsumoku concern went tits-up in about 87, and that's the era your FX comes from.

Kahler do a behind the nut stringlock that pretty much replaces the Bendmaster Deluxe one and would probably do the Bendmaster FT version.
It is probably a better piece of gear, too, if I'm honest as the OEM nut was made of pot metal and stripped if you looked at it hard.

I'd love an FX - it's the only Spectrum I don't have....
