Here is the background from my website
But to elaborate, whilst peabody did indeed patent the falling block mechanism, his device used an external hammer, whilst Martini used an integral coil spring and striker, that in itself partly crossed the self cocking patents of Westley Richards. In 1872 it all came to a climax with the legal wrangles between, Peabody, Westley Richard, Frederick Martini and the war office, who ended up paying off Peabody, telling Westley Richards to stuff it, and Martini changing his mind on the initial prize money and opting for royalties on rifles made instead.
That wasn't the end of it. Westley Richards became Martinis UK agent and patentee, setting up the National Arms and Ammunition Co, to make Martinis and Alexander Henry's (the rifling patentee) involvement with the Henry Rifled Barrel company, also to vie for Government contracts. Both were not asked to tender when contracts were awarded for 38,000 rifles in 1872, incensed they sued the Government for lost royalties, as the Birmingham Small Arms, and, the London Small Arms companies had been told by the Government that they were exempt from paying patentee royalties. After three years they actually succeeded in their case, and were awarded huge back payment in royalties, initially the government appealed, it went to Lords and they lost, having to pay out huge figures £10,000 for lost royalties. (Enfield was exempt, as it was not a private maker). Whilst it was morally correct, it was business suicide as the companies were completely overlooked until the early 1880's.
