Hello Spirel!
This dagger has the most camera shy markings I have encountered, they just won't take!

I'll try again tommorow with natural light. I agree but the use of "Austria" would indicate post WWI, Since before it was Austro-Hungary or K.u.K. About the font it looks like a very plain text set like the type used on a rifle or pistol, almost identical to the "Courier" font on the computer. It is stamped only moderatly deep and is quite worn from use. I have seen a pistol from OWA that has "made in Austria" from 1920-1925 but was ment for both export to England and America as well as domestic sale. Personally this knife is priceless.

P.S.- While were on WWI, You would'nt happen to know anyone who could tell the age of a German Trench Dagger would you? All the data I could find on the old internet is confusing at best and contradictory at worst!
