Hi Lynn. Couple of things.... I call your drum a Standard, but don't know where I picked up that term. Perhaps it is referred to as a "standard" model vs the "Deluxe". (Which is a BB.) I am no expert, just an enthusiast, and will defer to Curotto or Bun E. They would be a definitive source.
They are also described today as the two piece heavy brass shell. I believe the triangle shaped bearing edges soldered to the shell contribute greatly to the sound. The original single flange hoops really allow the drum to open up. The brass triple flanged hoops are much more user friendly for your sticks and give a subtle hint of control which to my ear, is just right, especially for a drum that is getting played (like yours will be). Diecast hoops would shut the drum down even more. (Just my subjective experience due to experimenting.). Try the hoops from your Jazz Fest and compare the two.
I just checked my 8 lug 5x14 to see how it is set up. I have a Remo Vintage series Amb on the batter and a hazy Amb snare side. The wires are Ludwig 12 strand wires (the same with 16 strands still buzzed). The Ludwig wires are lighter and play a bit brighter than Puresound 12 strand. If you look at the photo you can see they fit the snare beds perfectly. Plus the script "Ludwig" looks great with the drum. I think you can still order them from Ludwig. I guarantee that when you play the drum you couldn't tell it didn't have 20 strand wires.
I can't remember for sure if I have 12 or 16 strand Puresounds on the 6.5, but I am thinking 12 strand Puresounds. It is on loan for a friend to enjoy, so can't check.
I think your dating is great and far more accurate than my time frames. (Nice work.). I think of the 8 lug with pioneer t.o. as mid 20's, the 10 lug versions are later 20's and going into the 30's they switched to the time piece t.o. Like I said, there are others far more knowledgable than I. Hopefully they will chime in.
