Updated through online information from Josh Sellner. -- Originally tubular pneumatic. In a parish history published in 2007, K.C. Marrin writes: "During the pastorate of Fr. Edmund Hall, I was contracted to upgrade the organ to electric action, and clean and repair the organ as was necessary. [Fr.] Edmund [Hall] left before the commencement of the work and I completed the contract for Fr. Julius Muggli [pastor from 1979-1986]. Lead tubing was removed, and electricity was used to engage small magnets that activated the pipe valves. New keyboards were also installed, but the rest of the organ is pretty much in original condition."
