65 Note rolls were for the early player pianos, typically the push up players. Some player pianos in the early days had the 65 note player inside the player piano. Some of these were a bit universal in that they would also play both 65 note and 88 note rolls. These are quite a find.
Before industry standards set in to make the 88 note roll the standard, there were many sizes of rolls as well as number of notes. One of the early types was the Apollo Concert Grand which while an 88 note machine, the paper width was 15 inches.
