This seven-volume set of books titled Patents For Inventions (Small Arms), 1855-1930, has every British Patent registered between these years, in 8.5"x11" hard cover. This 7,980-entry reference was originally produced and published by the British Patent Office between 1904 and 1934 to assist inventors and the small arms industry. Each patent description is summarized and most are accompanied by the essential drawings. Several hundred entries are American and continental European. Also included are patents for auxilary and other special use cartridges and small arms accessories. The current publisher produced 1,000 sets, from a rare original, in the mid 1990's and they are now in use by professionals and the public in 24 countries. Less than 200 sets remain.
