Any ideas? I am clueless.....It's brass, the opening is grooved, and it looks to be missing a retaining clip.
You need to provide a better pic with something for perspective,,,,how big is it?
Pretty sure it's something homemade and I know the purpose but without better pics ,,,can't be sure
part for a musical instrument I do not know what kind
Here are 2 more pics now that it's cleaned up.
Well that totally changes things for me,,,,much smaller than I thought.
Put me in the clueless camp
Still keeping my guess the same
I believe you got the right ID Medic; nice call. I was in the dark til I read your first post, then did a little reading and saw very similar pics when I googled the various types of reeds. Someone here nearly always provides a good ID for puzzlers.
I wouldn't have known what they were either until I dug a stupid amount of them last year
Yep RM nailed it !! we call em SQUEEZE BOX REEDS LOL
