I offer a collection of 114 historical patents of accordions and concertinas, published between 1854 (!!) and 1920 in USA or Great Britain (all in english).
You will find docuemnts from Hohner, Galleazzi, Stratton (USA), Meinhold, Glier (Klingenthal, Germany), Gessner, Spaethe (Germany) and a lot more.
The patents are busy in most cases with various accordion constructions, concertinas or something like that.
All patents are complete, that means contain the full text and all (often very artful / detailed) drawings (see example). You will get a professional overview about this field of musical instruments, which you find nowhere in the world in this good quality / completeness.
Delivery is as a zipped file with a patent collection of pdf files (not printed, not a book). You need only the wellknown free programme Acrobat Reader or a similar one to open the files. You can also print each file.
Copyright of the patent collection has only the seller!
