Thanks guys for sharing your knowledge.

If I understand correctly Weipert is located in Austria in the border area with Germany so this gun was built in that general area using a German frame and a Belgian tube set and proofed in Weipert. Which is the Weipert Mark and what suggests Neumann Freres barrels?
What suggests to you it's manufacture to be during the WW1 era?
I see know indication of chamber length or anything that indicates at what load the barrels proofed at. Do marks indicate this information?
