Made for a period of some 26 years between 1960-1986, the Aeolian Company had eight basic models; Duo/Art, Pianola, Musette, Hardman, Cabaret, Sting, Sting II, and Keepsake. While the cabinet styles were all different, the internal workings of the player mechanism were virtually identical (except in the 64-note model). There are a few production changes over the years as Aeolian struggled to perfect the Automatic Rewind and Shut-Off sequences. However, there is one very unique feature about the Aeolian players that makes them extremely easy to identify, and that is the placement of the 5-bellow Wind Motor, which is ALWAYS to the left of the Spoolbox (in the upper half of the piano).

Since there were tens of thousands of Aeolian players produced, many of them are still in existence and a fair number of them still work. However, the mechanism was not made of very high quality materials and as a result there have been numerous problems with Aeolian players over their relatively short lifetime. Therefore, I have listed a number of links below which lead to various webpages that contain information about the instruments.
