Well... it could be one of several solid body types that Oscar Schmidt made in the 80's ... the Lancer or the Cutlass... they are both extreme instruments... the Cutlass got its name from the shape... a very edgy looking instrument... the Lancer was just as nice... both were made in a really heavy manner so as not to produce feedback when jamming.... i am in the process of buying one of the Lancer style... but would really prefer the Cutlass....they also differ in the fact that the Cutlass had screw on legs as it it quite heavy... but Oscar is still making new versions of electric autoharps.... so if you could please post some pictures of it if you still have it and i call tell you more about what you have...
