Tom thanks for all the research that you did and the time spent doing so. I have to say, that I am really falling in love with this weapon and hope to have some targets to show by the end of the month. The only issue that I have on a rebore is that, it, in my mind, should have whatever caliber it originally was, on the barrel in some place or taken off or marked off and this one doesn't, which leads me to believe that Schulltz and Larsen replaced this barrel. The other thing that I have looked at, is in my understanding, when S & L went for the civilian marksmanship market, they converted the rifles to single shot. The rifle is a Copenhagen make but with no markings on the breech, crown etc. On your rear sight, is your sniper rifle the 1925 one? The cutout on mine is very professionally done where the adjustment knob is. My other thought, is that the upper handguard is serialed to the gun with no provision for a rear sight like the carbine, and of course, the long rifle didn't have that wood there for it to be a cutdown. Sorry to ramble on, but this thing is getting to be more of a mystery to me...thanks again...Eric
