My guess is that this is a Pearl made drum. Could be wrong, though. The bottom hoop looks pretty hefty, could be aftermarket, like I suspect the strainer is.
I wouldn't go all out and spend the money on Puresound wires. A new set of cheap 20 strand wires will be all you need. Maybe if you really wanted to gussy this thing up you could go with the German made ones, but dont think it's neccessary. I mean, if you had an old Radio King or something really special you could justify spending the extra cash on the wires, but for an old import drum, it just doesn't make a lot of sense, and I dont think you would even hear that dramatic of a difference in sound. Please keep in mind that this is coming from someone who loves these old Japanese drums.
And, man! you gotta love that wrap! The drum looks like it's in really nice shape overall. Have fun getting it back up and playing. Post some more pics when it's all together, if you would.
