Hello, I'm here. A couple of thoughts (some of which Raimey and Keith have covered already):
This is a Daly hammerless model 125. The crossbolt (vice dollshead) and the lack of ejectors, combined with the relatively plain engraving pattern, peg it as a model 125. As Raimey mentioned ,this is a Heirnch Lindner made gun, but I I would put the production date a few years later than Raimey's estimate at circa 1895/1896.
Turning to the barrel flats, I know of no national or independent proof house that marks its proof testing in this manner. I have never seen anything similar on any other Prussian Daly gun. To me these appear to be someone's basement efforts. The rest of the proof marks look to be typical German 1892-era proof marks for a tightly bored 10 gauge gun.
As Keith mentions, this appears to be a damascus barreled gun. The rib marking that has been partially obliterated would read, "Charles Daly Fine Damascus Barrels". My hunch is that whoever marked the barrel flats, scratched over the rib inscription (and also likely blued over the damascus pattrn barrels) in an effort to conceal that fact that this is a damascus gun. (Side note: In the early 2000s, I sent a big Daly 10 gauge hammerless damascus gun over to the UK for proofing. It passed the modern magnum proof with a yawn.)
In term of the rest of the gun, the pad is (obviously) a replacement and the forend tip has been significantly reworked, likely due to the loss of some of the wood near the ebony tip.
I'm happy to answer any questions that I can. Here is my email address if you'd prefer to chat offline: kengeorgi@gmail.com
