Oscar Schimdt Appalachian 21 bar diatonic autoharp in the single key of G. American made in the early 1970's. It is in very good shape.
Strings and felt are good as well.
This has a resonator back, which means there is a separate back (applied by owner) to leave a space between the the 'harp back and the player. This helps to increase the volume of the autoharp.
