I've been doing some research on Michael Giles's drum kit during his time with King Crimson (1969) and need help in identifying a clamp of an unknown make. At this point, I've established that he played a Ludwig Blue Note, although there were a few changes from the configuration listed in the 1967 catalogs (the most notable being the swapping out of the seat case with a porto-seat, and the wooden snare with a supra-phonic).
Due to the height limitation of the BD cymbal mount near the hi-hat, an extension was assembled from (what I suspect to be) a leg from the unused 16 x 18" floor tom and a clamp connecting one half of the mount with the other. Since there was some added Ludwig hardware, one would assume that this clamp was their doing, but I don't see a similar part in the 1967 catalogs.
Interestingly enough, it appears Ludwig made something like this recently, the Modular Adapter Clamp, but whether or not an earlier version existed I don't know. The only other conclusion I can arrive to is that this wasn't a Ludwig part or wasn't even made by a drum company but originally intended for some other purpose.
Any ideas?
