I just don't think it will be in their ledger, but I hope I am mistaken. So this smokepole will be judged solely on its own merit - a Delcour DuPont sideplated A&D Boxlock, possibly retailed in Vienna by J. Springer, which might add couple $100 to someone knowledgeable or smitten¿
I agree on the tumult of the region likely adding to the oddity of the gun and can absolutely see them trying to stay afloat by offering lower end guns... and at the same time not putting them in the ledger. Or... for that matter... someone else might have simply decided to stamp it themselves and retail it somewhere completely unrelated!
I'll have to get a photo of the top of the barrels... but the stamp up top is not well done, light and off center. It doesn't match the quality or depth of the rest of the markings. Also interesting is that it doesn't say Joh. Springer Erben or even Joh. Springer. But simply "J. Springer"
It is in nice shape and would make a nice gun to carry after quail or the like with loads from RST or Polywad. The dimensions are decent and I bet that your pricing is spot on. When it sells I'll post the result here just to close out the string for the next fellow.
Thanks to all of you for your help on this one. I learned a lot and that's what I love about playing around in this particular sandbox.
Thanks
Shane
