So, no marks on the underside of the barrels or on the water table (the flat portion of the action the barrels sits on?
In your photo of the left side, there is SOMETHING written/engraved, but I can't make it out - looks like at least two words/names starting with an "A" and then an "N" - looks like New York for the second line
The A part also looks like it has "Co" after it, so A(name) Co, New York
The stock is thrashed with too many cracks to be shootable, even if the action was able
Without proof marks, I would guess it is US, not European
a nice wall hanger in any event
