Please help identify this 1800s organ:
I'm trying to learn about this organ. Can you help identify it, or tell me what to look for to help do so? There is one blank recess just below the music stand. I can't find any actual identifying marks so far, but I understand it was built in the mid 1800s.
Edit: Thank you, it is a Geo H. Ryder from the late 1800s.
