Dave Drew has some 10 lug rims. Were used for Superten, but should be the same rim, unless the profile changed slightly.

Thanks Amos but Daves too expensive. Even Poopers prices are better. I thought I'd try here first. Thanks

Daves rims should not be correct. You are looking for a mid 60s topper. Daves toppers are late Big R flat top hoops, or at least that is what they should be.

Thanks PM I was getting desperate. Yes its a 64/65. A 7 line Dyna rim would work.

The flat top hoops of the late big R era is something only recently nailed down. Between Tommy at the ROF and myself with our interest in the late issue XP10 Dyna-Sonic and SuperTen snare drums, we made a few previously unreported observations, one of which was the hoop change about 1982. And that is why I doubt if Drews top hoops are of the style you want. The shoulder profile is classic Big R Rogers, the top flange is flat. If you happen across a tall boy Dynahoop... I am in need. Have been for a while. It would be for my #2811 Beavertail. Which is an extremely low number for a beavertail.
