DESCRIPTION:

On this original lithograph print from 1932 (includes original specification sheet), Armstrong Siddeley Motors Limited patented an improvement in the cooling of internal-combustion engines. Armstrong Siddeley was a British engineering group that operated during the first half of the 20th century. It was formed in 1919 and is best known for the production of luxury vehicles and aircraft engines. The company was created following the purchase by Armstrong Whitworth of Siddeley-Deasy, a manufacturer of fine motor cars, that were marketed to the top echelon of society. After the merge of companies this focus on quality continued throughout in the production of cars, aircraft engines, gearboxes for tanks and buses, rocket and torpedo motors, and the development of railcars.

All patent lithographs sold by Maymont Group are 100% ORIGINAL.

These documents are NOT reproductions or posters (patent art).

These are the original lithographs found in books obtained from the Patent and Trademark Office directly.

 

In the 1800's and early 1900's, inventors would submit a detailed drawing of the invention and/or improvements to the patent and trademark office. Once received and if approved, the Patent office would then send a letter of confirmation to the inventor and begin to take that drawing and etch it into stone in order to create and print this linen-backed lithograph. These documents are the original hard copies that were created by the patent office's artists, and act as patent examiner reference material. With that being said, these are 100% original and are the only physical copies in existence.
