I have to ask... is your pickguard starting to "go", up near the top? It almost looks like there's some greenish corrosion of the gold finish at the tip of the Tremotone handle. If the guard is out-gassing, I hope you've already removed it. That gas is nothing to mess around with, which I've unfortunately learned from experience (the pickguard in the above photo of my L5CT did the same thing).
Thanks for the heads-up. The guitar is at the shop getting a fret dress and setup ... will check.
Hey, is your '62 Sheraton the one that was for sale at Vintage And Rare (actually photos are still posted there) last year? If so, you just beat me to it.
