Mick - those early round badge drums had badges that were tacked on. Like this one:
The bass drum had a large version of the round badge that was secured with a traditional grommet. Like this one:
As you can see, it will cost more for two replacement badges than you paid for the drums!
Go to Precision Drums website, price out three pre-cut pieces of Gold sparkle wrap and make your orphans a kit. There is also a 16"x16" RB shell for sale on the bay:
Finish that one off, add it to the kit and you're in Round Badge Heaven.
You can use a new Maxwell Rail to complete the bass drum. It will be a dead fit for the holes.
I started my RB kit with the same three drums you have, snare, tom and bass. I added the FT later and re-wrapped the whole she-bang. This is what you can end up with: Only in Gold!
