Hello, I have a Abrim Shasko banjo wall clock that i was told is the only one that exists in the world. The Abrim Shasko banjo clock is an exceptionally rare find. Only two of these clocks were ever made, and one was destroyed in an explosion in Albany, Massachusetts, between 1986 and 19881. The remaining clock is made of mahogany-finished wood and features a lighted design1. Would you be able to help me come up with a valueation?
