Swiss is NOT Swedish. Husqvarna is a Swedish company.
Underlever hammer doubles could be Husqvarna, or one of many Belgium makers.
Not sure when the Husqvarna underlever hammer guns were first nitro proofed, but in the late 1890s or shortly after 1900 is what I remember. None of mine, including up to WW2 have proof marks, which is SOP. Proofing was to what today is essentially CIP standard. Very few, if any, of the underlever hammer guns had 70 mm chambers, ditto for the top lever hammer guns from before WW2. 65 mm chambers, NOT 2,5 inches, was the standard in Sweden.
I stick to reloads with listed chamber pressures of about 10.000 psi or less for the fluid steel barreled Husqvarnas. FYI, Remington black game load 16 gauge ammo has 67 mm hulls (even though marked as 70 mm) and can safely be used in 65 mm chambers, per CIP regulations. Fiocchi 16 gauge 1,0 oz loads I have bought also have 67 mm hulls. I also cut Federal and Winchester 70 hulls down to 65 mm and use hartin crimps.
