Located in Missouri, Bass/treble break at keys 36/37. Pitch is A435. Bass is: 4'',8'',16''. Treble is 2'',4'',8'', &16''. The sub bass is 36 notes with the upper 24 being in the reed stack with the lowest 13 being in a separate block in back. The reason it is totals 37 is because the bottom C is in both sets and sounds together. The center door glass is Bohemian cased glass. The dark purple color design was made with gold and fused to the clear glass. After this was done, the pattern was layed out and the purple layer was etched away revealing the pattern. It was very expensive in the day and not made anymore.
