As I continue to refurbish and rebuild many of my vintage snare drums, I've taken the time to go a step further and catalog the weight of some of the shells. Those of you that get involved with the minutia of all this may appreciate this info...
All shells are weighed on a Pitney Bowes electronic scale calibrated to 70 pounds.
Rogers SuperTen 5x14 COS (bare shell) 3 pounds, 6.5 ounces
Rogers Powertone 5x14 COB (bare shell) 2 pounds, 13.5 ounces
Ludwig Super Sensitive 5x14 Ludalloy (bare shell) 1 pound 14.5 ounces
Even with the extra holes for the SS mechanism, I'm sure that a Ludalloy Supra would pretty much weigh about the same.
Hope you find this information helpful!
