The earlier Superstars from 76 to early 79 were 4 ply 6mm shells with re rings and were all suppose to be Japanese birch.From some time in 79,Tama started making supes with 6 ply,9 mm shell with no re rings.
My superstars are vintage 77,and are 4 ply 6mm shells with re rings,and the finish is called walnut( the same color as super mahogany) and it's a satin poly finish.
Traditionally except for the 76 9600 series or customs made drums,superstars were stained and ply coated first in a matt finish,and then in a gloss finish.The interiors of all of these drums were also stained with the same stain as the exterior color stain.
That's what confusing about that kit.I've never seen the interior of the 76 9600 series drums that were wrapped,so that may be factory stained,since these series of drums were all birch,no mahogany,and no maple.Just 100% birch.
