Hi, thank you for your question! I have completed thousands of musical instrument appraisals and will be happy to help with yours.
Any photos available of it you can attach here?
Thanks for the photos. Two of the three weren't really clear enough to be seen but checked out the one which shows the organ overall.
In regard to prices these organs are selling for, they aren't too high. The market for old pump organs is very small. There isn't really a musical purpose for these instruments which helps keep prices low.
While they are old, they aren't really priced like antiques. In the current market, I would recommend a selling range of $100-$200. Best wishes!
