Dan/Dave...
The pictures help quite a bit... but there is still a tad of a mystery on this drum. Here's why:
This shell looks to me to be a Dynasonic and not a SuperTen. SuperTens did not exist in Maple during this era, and, when they were finally offered in Maple, they were made up using 10 ply shells, no reinforcing rings. Also, Dan mentions there are no snare beds... well that was also a Dynasonic attribute, although technically speaking, the Dynasonic did have beds, but they were just .004 deep... the thickness of a business card! Anyway,
The badge is still the sticking point... the oval SuperTen badge was gone by 1976 when Rogers introduced the Big "R" badge... and the SuperTen WAS NOT available in a Maple shell until 1982. And as mentioned prior, the shells were 10 ply, no re-rings. So...
What exactly do you have here Dan? I really think it's a Dynasonic shell with the addition of a SuperTen oval badge. One way to tell is to remove one of the heads and count the plies of the shell... I bet you're going to find a 5 ply shell with 5 ply Maple re-rings. Also, can you see three pin holes where a script logo badge would have been attached? If you do have this configuration, it is a wood Dynasonic shell... but WHY the SuperTen badge?!
It has been mentioned many times that the American drum companies would build to order, or custom "one of's" from time to time... but Rogers didn't participate in that for the most part... but you just never really know.
I would keep it Dan... it is unusual, and I have no doubt it sounds good. I would like to know what you find when you pull those heads though!
