rigbymauser,,i would say it is not an original oberndorf sporter, as i dont think any were made with side panels and it looks more like a typical cigarette mauser ,, these are well built and a lot of gun for the money i had about the same thing in 8x57, i bought it about 25 years ago when i first discovered how nice these german sporters were for the money ,,if you go to SIMPSONLTD. site you will see few guns that have the look of oberndorfs but are not,my guess is yours is just built of a military oberndorf action ...paul
