it doesn't look to match any of the W/Fs. colours that I can see - it's a very insipid sort of washed out ruby, but not how ruby should look, and it's not near to the ambers either.
The factory did make cog-wheel patterned feet on some other designs, but I don't see any of that pattern on the threaded pieces in Jackson.
Might this have been an experimental piece perhaps?
Where's Nigel when we need him?

How was this piece purchased?
