I used to tune a gutted player grand with the name "Welte-Mignon" for a customer who fortunately no longer has it. It was in rough shape. This particular piano was obviously of American manufacture and had an unusual Wessell, Nickel & Gross action with the backchecks mounted on auxiliary wippens. The body of the piano was unusually thick (top to bottom) apparently to allow the pneumatic stack to be mounted inside the action cavity. I think it had dowel capstans. Welte-Mignon was the name of the third major style of reproducing mechanism (after Duo-Art and Ampico). Bill Maxim
