Hello, here is Julekpl again.
Thank you for your information last time regarding the Steyr 1917. I won it at auction, and it seems to be firing capable. I have taken it apart and cleaned it as well. Even the removable barrel has the same serial (2733s) as the rest of the gun. I would like to take it to the firing range, however I don't know which 9mm bullets to use, the Parabelum (if "Germanified") 9mm, or the Austrian (is the Austrian 9mm bullet any different than any other 9mm?) 9mm. I have not seen any German signs on the gun, however there are many letter "K" in certain spots. I have also seen a few Austrian eagles in places as well. I have added a few pictures, and I have also taken a picture of the bore. Is it possible to tell if it was changed just by looking at the bore?
