I found the bar itself in my case but not yet the collar it attaches to - which is the important bit really. If you can give me till the weekend I'll go through my music box and see if it's in there.
No rush, buddy, I'm just in the middle of a customising, er, Jag... Many thanks!
Waiting to hear from a local guy about installing a pick-up under the tremolo for sexy behind the bridge sonics... I'll be using the controls on the top horn to turn the magic on and off, etc...
Did you have any luck, B?
