Dan,
I love those maple hoops. I know it's not period correct, but I have always loved that look. I have a 1962 20" Slingerland BDP bass drum on which I put lacquered maple hoops and everyone comments on how much they like it.
JC, I am sure if you do some research you can probably figure out how to finish those drums yourself.
Actually, I think that is a brilliant idea. Those satin, flash, mist or whatever they may be called wraps seem synonymous with Big R drums, but since no one knows where to source them, a veneer with one of your experly applied, serious laquer finishes will look fantastic. I would suggest a really deep clear coat as the matte finishes didn't show up until fairly recently.
