Wurlitzer Caliola by Stinson Organ Company

Here is an (I presume) early Stinson Caliola (copy of the Wurlitzer Caliola) from the late 1970s? It uses Wurlitzer Unit Block Valves. It has no additional instruments, just the organ pipes, drums and cymbal. One note has a cipher and I traced it to a unit valve which I will be replacing. You can see paper in the pipe mouth to keep it from speaking.
