Red onyx wrap that is probably as close to your original as you are going to get is available at Precision Drum Company. Attached is a snare drum recently refinished in that material. I received this drum as one that had already been done in a Ludwig pattern black diamond pearl. It is much closer to the look of an original Rogers drum now with this wrap. It is very close to my Cleveland red onyx snare that I found a few months after doing the rewrap.
They have good instructions for applying the wrap if you're even reasonably handy. The wrap is not inexpensive, but is well worth it if the existing wrap is in bad condition. It is expensive to have them do the work of applying it, but they will do it if you need it and can afford it. The quality of their work is reported to be very high.
The existing wrap can be very difficult to strip (if in fact it can't be saved by cleaning and polishing with special plastic polishes from Novus, which is available on line).
If it ends up being rewrap, drop me a private message through this forum and I'll try to give you a rundown on the process.
