Die Patente stammen aus dem Jahr 1921. Das Bild stammt von einem anderen Baron’s Pipe Filler (Nesbits Auctions). Prägungen PATENTS APPLIED FOR ohne Patent-Nummer sind älteren Datums. Der angebotene Filler darf somit auf vor 1921 datiert werden, möglicherweise sogar 1909 und gehört damit zu den ersten Exemplaren.
Zur Firma Carreras gibt es auf Wikipedia interessante Infos:
… In 1904, an allied company was established. Called Carreras and Marcianus Ltd and operating from St James’s Place, Aldgate EC3, the former Baron Machine Company works, the company’s purpose was to commence production of machine made cigarettes. During the last six months of 1904 three brands made their debut, including Black Cat, the first cigarette in the United Kingdom to contain coupons which were redeemable for gifts.
In 1905 yet more brands were introduced such as Chick, Jetty and Sweet Kiss and Carreras began coupon trading in Black Cat. Business prospered and in 1906 additional premises were opened nearby, introducing new brands such as Carreras Ovals and Seven Up. Baron chose many novel schemes for the promotion of Carreras’ pipe tobacco and cigarette brands. In 1909, the company introduced the Baron automatic pipe filler in cartridges, which revolutionised pipe smoking and sold by the million.
