Hoop with round hole

[Ralf]

Hello,

Shortly I came across a bunch of spare parts, amongst them are two hoops with round holes for the tension screws.

Any ideas which producer used this limiting hole for the screws?
(Don't judge by the lug below - both came not mounted together at a drum.)

Thanks.

They are Premier from the 70's through 80's. They were used on the lower lines that didn't come with die cast hoops. They were also used on Olympic and Beverly drums which were made by Premier. What size is it and how many lug holes?

Thanks.
I have a 16"/8 lugs and a 13"/6.

Those would most likely have been for Premier or Beverly branded drums. The Olympic drums usually had fewer lugs than the higher end ones.
