Pearl international 1985 series drums .

I am looking for the exact or similar to this . I have been looking for arm for my other bass drum for a long time. I came close and I never got one. I think it might be a 7/8 or 1/2 inch pipe. Really not sure.

Arm here is the earlier one that hasn't got a Pearl stamp on it

I am not having any luck what so ever on FB drum page's .
