"F. Beesley patents 425 & 14488 of 1884 and H.A.A. Thorns patent of 7242 of 1894"
Regarding Lancasters, these patents are unique in that two different guns can be made using this design...a sidelock and a "body action". The body action looks like a A&D type boxlock, but it's not...its mechanism is entirely different from the a&d.
I'd like to see the inside works on this Crecent/Triumph and see how it really compares to the Beesely/Thorn patent. The compressors on the action flats look nothing like the compressors on a Lancaster, and the barrels are also lacking the compressor bar fitted through the lumps.
This action actually, to my eyes anyway, closer resembles the Smtih easy opener used on Churchills, Rossons, etc.
