I think this parlor organ was built around the mid-late 1880's. The case construction is matter-of fact, built up with 3/4" stock over a panel of thin veneered plywood; it's not the heaviest or most secure way to build casework, but it is very efficient. A lot of glue joints were bad, and the little storage cubbies were destroyed, but the organ was salvageable. The sound board had split in many places and the reed cells had come loose both front and rear. I found the bellows to be quite interesting, using a 3/8" panel of plywood both as the fixed reservoir board and the back panel of the cabinet is a significant savings on material and weight. I was a bit concerned that the feeders were so shallow, but in playing it proved not to be a problem; their space to open was limited by the storage closets to either side of the knee space. But these were a fixture for Shoninger, and probably a vital selling point.
It had an action with 4 rows of treble reeds, two rows of bass reeds, a 13-note sub bass, and the 30 note set of tuned bells from g below middle c to the top c.
I also had to deal with cleaning the casework.
I did a lengthy demo of it on my youtube channel; as always, forgive my bad notes. Because of the bells, this has become one of my most popular videos. This organ literally has the nicest Voix Celeste stop I have ever heard.
