Not with those pictures, they're too small and I don't know how to blow them up and, I'll need to see the proof marks. Pull the gun down and the proof marks will be on the barrel flats and probably on the water table. Might be a couple up the barrel a little bit from the flats.
Roux underlever action, typical hammer combination gun from the late 1800's up to shortly after WWI. It's entirely possible, indeed probable. that Oberhammer was just the retailer. It was more than likely made in either Suhl or Zella-Mehlis. Proofs should tell the story. Hard to tell from the tiny photo's but it appears to be in remarkable condition.
