Hohner Double Ray (aka black dot) BC. A lovely example from the 1960s. It is the typical 1950s/60s shape with curved metal grill similar to the Erica, but in the scarcer black celluloid finish. It has modern bass and a limit to the button travel on the right hand side, The buttons are the nicely rounded type that Hohner only used for a short period. Plays beautifully.
