I have a metal shell snare with 8 tube lugs. The shell appears to be 2 pc. has a flush mounted duplex flip down throw-off that attaches with 2 screws, one each side. The drum is nickle plated brass (heavy). The bearing edge is completely folded over to the shell.

Any idea of the age of this drum, possibly a value range too. I can't find much info on Duplex.

Thanks!

Dave
