Two pics attached. One is of a cymbal stand topper nut with a rotating 'clip', to eliminate the wing nut on the top of the stand. I believe Zildjian marketed these -- these are for 6 mm thread. Anyone know a who what when where?
Same for the picture of the stand. Flat based stand, with wing bolts that match the Ludwigs. But the fastener for the top tier is a different style. It's not drilled through the tube; a pretty good idea, really, cuz one less threaded hole to strip.
I like the stands --and those wing bolts are no longer available, so that's a real bonus.
Ideas??
