If you was expecting to see a button accordion in this article then you might like to know that a melodeon is also a 19th Century reed organ with foot operated vacuum bellows. It differs from the related harmonium which uses pressure bellows.
Today I am featured two such instruments made by Geo. A. Prince & Co. of Buffalo, NY.
The first one is dated 1858 and has a buy it price of just $345 (£183). Too bad that it is for local pickup only, and in Los Angeles otherwise I would be sorely tempted. I find it heartening to find 148 year old instruments like this are still available for reasonable prices.
This second one is slightly earlier in date and is even more impressive.
