hopi, I don't understand your Italian posts. This is an English language forum. Why don't you post in English, as everybody else does? Ich poste ja auch nicht auf Deutsch.
As your rifle has German pre-1940 proofmarks it was definitely not made by Peterlongo in Innsbruck, Austria, but by someone in Suhl or Zella – Mehlis,Germany. If there is the Peterlongo address somewhere on barrel or receiver, it was made in Germany for retail by Peterlongo. If the word "Peterlongo" does not appear on the rifle, it may have been retailed by anyone, including Peterlongo.
