In wearing the number 754, it is a very early 2nd series & it would date to 1892-1893. All that Magnum chicken scratching is waaaaay past the original effort & I for one know not where it might have been tested. But it was an English speaking effort.
https://www.gunbroker.com/item/1074798976I'm wondering if there ever was any actual MAGNUM NITRO PROOF load testing... or if that is just some rather uneven number and letter stamping... applied in a different font and size than anything else on the gun. There is no indication or stamp from a proof house, and no indication of either the alleged nitro proof load or max. nitro service load. I could certainly be wrong, but this looks like someone's crude effort to make an old Prussian Daly shotgun into something it was never intended to be.
Also somebody blotted out the writing behind the Charles Daly on the barrels, but can make out the first letter of K
and I see a L near the end. Krupp Fluid Steel Barrels. ???
Nope, not Krupp Fluid Steel Barrels... not even close. It is evident these are blued-over Damascus barrels, with no etching to bring out the pattern. The barrels may retain 90-95% blue, but it sure as hell ain't original blue. Hopefully it was rust blued and not hot salts blued... but that rust around the front sight bead could be a bit of leakage from bluing salts residue.
You might want to go back and edit that Gunbroker description a bit to reflect what this really is. I put it on my watch list to see what happens, but I won't be bidding. It sure would be interesting to know the chamber length, bore dimensions, etc. This one has been messed with, in a bad way, and it doesn't take a Prussian Daly expert to see it.
