Notes

In 1878, the firm of Charles Lancaster Gunmakers, previously run by C.W. Lancaster who died in that year, was acquired by Henry A.A. Thorn from his widow. In1881 Thorn patented an action for two and four barrel guns, he would subsequently use this patent in the manufacture of both shotgun/rifles and pistols.
The pistols were designed to take a veriaty of calibres, but in the main they would be for the four barrel pistol .455 and .476 government cartridges and for the two barrel pistol the .577 short Snider or Boxer, they were also fitted with Lancaster's oval bore rifling.
In all about 712 four barrel pistols and about 234 two barrel versions were produced between 1882 and 1897.
