Pounder!...
Mine is indeed chrome, as the higher end drums all were during this period of manufacture. Chrome was EXTRA back in the day, which is why there seems to be so many more drums in nickel. Buddy always had chrome hardware on his sets, but most of the public bought the slightly less expensive nickel.
JFBL's drum is most certainly a re-wrap... that is NOT a WFL WMP wrap. You know what though, for the sake of argument.. ( and I mean nicely! ) .. JFBL:
The original wrap was actually tucked into the inner ply on the inside of the shell, making these era WFL's very difficult to get completely stripped.. meaning.. you probably have remnants of the original wrap still inside the drum, yes? Then... check the outside seam and see if it stays on the outside of the shell as any other wrap usually is. Pics would be GREAT!!
