I looked at a piano today that someone got at an auction a chucrch had. It has 64 keys and 5 octaves, keytops are rounded over. It is about the size of a small desk . The serial number on it was 379868 and various dates stamped on some of the key sticks suggest it is from the 1940's.
One stamp reads New Scale 8-23-46. A number stamped in the keyslip reads 64 keys. I think it
could be a piano that was made to be portable to entertain army troops or to be used for church
services in the field. Everyhing about it is portable - the legs are tapered screw on legs and the pedals are large tapered dowels. It is rectangular in shape with hammers that strike
down, dampers similar to a grand. The plain steel strings are doubles- no triple strings.

It looks like some work had been done on it and
overall is in pretty good shape. I am not sure of the best way to tune it because of the way the pins are located in relation to the case. An extension on a tuning lever seems like the only way or a T handle with an extension bar on it for
leverage. Has anyone out there ever seen one of these puppies and/or tuned one ?

Maybe it belongs in the Smithsonian since it seems pretty rare...
