GG375,
Mine was also bought used. It was built with 470NE and 9.3x74R barrels as they have the same serial number as the receiver. The previous owner added a set of 7x65R barrels which you see in the picture between my sons gun and my future son in laws gun.
All three sets of barrels came with Ziess diavari 1.5x6 scopes. The 7x65R and the 9.3x74R both have claw mounts and the 470 had the scope added later and has a pivot mount.
After I bought it i had it restocked left handed.
I'm thinking of adding a set of shotgun barrels and have a one gun set for any animal, anytime, anywhere.
