Most Stone drums of this era feature a metal badge affixed to the batter side counterhoop. Interestingly, while this drum has a makers label with a strong date stamp and serial number, it has no badge. This is likely because Stone was in the process of changing over from an older version to a newer badge which included lettering noting their recent incopration. Also, the Master-Model specific badges installed on most examples had not yet been introduced. While there are pencil markings present inside of the shell and underneath the counterhoops, they are not consistent with the numbering system later used by Stone to keep track of the total number of Master-Model drums produced.
