I have a set of red sparkle Stewart drums that my parents bought for me around 1968-1969 at a local music store. I have maintained these and they are in remarkably good condition for their age. In recent years, I have bought a set of drums to replace these and am considering selling the Stewarts. Could anyone provide me with information on the value of these drums or point me to a resource guide that I could make that determination.

Thanks so much for the help.
