The clamshell you need for replacement might cover the extra holes.... they will be there (bummer) but perhaps hidden by the correct strainer.

That is a sweet RK! The wrap is nicely mellowed, the chrome or nickel, looks like it is in great condition. The issues more than likely melt away as soon as you begin the roll, I'm sure.

I hate it they did that, but when you do replace the strainer with the original, would you keep me in mind for that one? It is an early Star strainer, from the early to mid-60s and I would like to have one of that model. I have all the others, but this one, and the paralell, of course. What does the butt plate look like? Is it the Star part?

You mean the one it currently has? What do you need to ID it? It does say "Made In Japan" on the fixed part, but no markings on the moving part. You get first dibs if you want it.

Also, I know the shiny parts would polish out nicely, but do I want to do that (pull the hardware off the shell, polish, and reinstall) or leave it alone in it's natural aged patina?

Sweet old Radio King! It's a Super Gene Krupa model from 1944 or '45. The "Super" designation was given to drums with the strainer commonly referred to as a "clamshell" today. The badge on your drum is aluminum because other metals were conserved for wartime military use.

That is a personal thing. I, personally, tear each and every part down as far as I can and deep clean each little nook and cranny. When they go back together, you will be amazed how absolutely stunning it will look. It takes time, but man, a drum like that deserves to look it's best!
