Good evening and Happy New Year to all!

I wish you health first and then all that you wish to yourself!

I was told those are Slingerland middle parts of cymbal stands

I found here something similar, 66 cymbal stand but without memory rings

I have 2 of those parts, they are in great chrome condition and 7/8" in outer diameter and 3/4" on the top, under wing screw

Total length of first one is 22 and 19/32 "

and second one 16 3/4"

Are those Slingerland parts
