Hi,
I just wanted to find out the brand (Rogers, Gretsch, Ludwig etc) and decade (60s, 70s etc.) for these rims. A magnet sticks to all the rims so I know their not brass and are triple flanged with top flange directed outward. The rim's size are 12 inch, 16 inch (taiwan), 13inch, 13 inch (taiwan) in the attached order. I believe that all four are made by the same brand because they look the same except sizes. Thank you for your assistance.
Regards, Robert
