Ours were stainless steel. They were like walking around with three garbage cans held together with rope. At least the next year the high school had COW Slingerland tenors in 12/14/16 and those things were built like tanks.
That would explain the source of the 22” triple flanged hoop. I’ve never seen marching tenors that large and couldn’t image carrying a set but my jr high had a set of stainless Ludwig tenors that I (unfortunately) carried. They were 14/16/18 and were undoubtedly the worst drums I’ve ever played...
Definitely not the best way for the band to handle the situation. You’ll be in a better place not having to deal with “friends” like that.
May they find themselves backing Corey Feldman on a tour of midwest dive bars.
Though it no longer exists, here’s a photo from flyover country for you ‘coasters. I remember seeing this painted on a building in Dodge City Kansas, the original home of Evans. A bit has changed since then.
I have several Sonor mounts and the tubes all interchange between my 60s teardrops through my Acryl drums, the latest of those being manufactured around 1977. As dingaling mentioned, it’s possible Sonor changed those during the Phonic run.
