That looks more like an organ to me than piano it seems to have stops on it?
Is it an organ? See, I wouldn't know, I am basically musically illiterate. At first I wrote "organ", then I changed it to piano. I think you are probably right and I'll change it on the graphic. :-)
That is an antique pump organ snugs. You have to pump the two foot-pedals which creates an air vacumn and makes the keys play.
