So indeed it was noted as passing proof using the >>Unique<< powder. One has to keep in mind that the Proof Facilities lagged woefully behind technology. I would guess 5 years to a decade. It just took so long to enter & pass legislation. 1st the bill had to be penned, entered & then you bribe 1/2 of the governing body & threaten the other 1/2 to get something passed. And it was not for the Protection of the Public; it purely for commerce. After 1891 when Germany devised some prooflaw as sort of a stop gap measure to try to keep in pace w/ the English & French, Germany closed the door on Belgian tubes until Belgium could get their Proof House in Order. Then & only then would one see change in Proof Law. Gun Powders and Steel Technology greatly outpaced Proof Law in any country.
But this platform looks to have a Jones Underlever Lockup? I for one would like to see what marks are forward of the flats up to the forend hanger.
