I found it fairly easy to source a spring from the junk box, and cut it to
length with a Dremel cutoff tool. I also lapped the tapered part of the
valve into the body a bit with rubbing compound, then cleaned and lubricated
it with silicone valve stem grease (didn't have any stopcock grease on
hand). Smeared some silicone on the new spring as a preservative, too.
Then a new flat washer and cotter pin completed the overhaul.
The result looked original and worked great for many years (probably still
works but I haven't tried it since the car got wrecked).
