I showed Jack MacFeetes a photo of one of the drums from this set and asked him to give me some comments I could use in this article. His comments were; "Five ply, maple birch. Color, Mohave Red, #84. 1976 Catalog shows this color in the Studio Ten Outfit, pg4. This drum made approximately 1978, Top hoop not correct. Memriloc hardware was developed through a collaboration with Dave Donoho and Roy Burns, and Rogers, of course mid 70s. Mounts are rock solid, stand up to the heaviest of hitters. Well made drums even though there were numerous moves during the Big R period, some of them very unnecessary, and quality at times affected by this. The hardware was about the best one could have at the time."
