We recently came across an interesting item at an auction and were wondering if you could shed some light on it's history. It appears to be a mathematical teacher's aid.
The label on the control panel reads, "Huber Pipe Organ Company, Trempealeau, Wis.
By pressing numbers on the control panel, the corresponding number lights up on the board. The dial lights up the functions. There is a button to light up the decimal point also.
Any information that you could provide us would be appreciated.
Thank you for your time,
Chuck and Marie Smith
