A320 glass cockpit software download. I got a post on facebook last night from a friend asking me to find the value of a gun for him. All's I got was this 'A byf 42, 1603 dd, Model 98' and no pictures! He also has no idea of what the caliber is. I am guessing myself here that it's a Mauser 98K and if I am right these were chambered in 8X57MM. Can anyone else give a little info on what these other markings might be and am I right as far as the caliber.

As for the value I know it is very circumstantial to the condition/shape/how original the rifle is. Many Thanks, Eric.
