I have Slingerland Radio King floor tom (16 x 16) (please see pictures). There is no badge. The drum has WFL brackets and legs mounted on it. My questions are: 1) What year is this drum, 2) Did it start out as a floor tom that was intended to have a cradle to suspend it that was later replaced by the WFL legs (as you can see in the last picture, there are pencil markings on the drum that suggest someone was planning to/did do some work on it), and 3) What is it worth (the wrap is tight, there are no additional holes besides the WFL leg mounts, the WMP wrap has, of course, yellowed)?
I would greatly appreciate any assistance you can provide.
