I offer a collection (researched / made by the seller) of 27 patents of the piano company Broadwood & Sons (Great Britain), published between 1906 and 1924 in the USA and Great Britain (all in english).

They are busy in most cases with piano technique.

All patents are complete, that means contain the full text and all drawings (see example). You will get a professional overview about the inventions of this company 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!
