So my son was gone for 2 hours and I couldn't help myself, so I opened up his gun and cleaned it and looked at all its internals. I do think the manufacture date is October, 2002. It was made in Germany. I think it is a large ring mauser commercial action that had the rear bridge welded up and then recontoured. Original markings were welded and dressed down. New proof marks and serial numbers are all that are present. Some of the goodies I found: Beautiful job done internally on the crossbolt. Action bedding was well executed. The gun is pillar bedded too. External bottom metal is some kind I'm unfamilar with. It is lightened on the insides of the magazine well with 4 reliefs on both sides. The bottom metal also has 2 action screws with 2 keeper screws holding the bottom metal to the correct depth for the pillars. (all screws engraved) The receiver has one germany proof mark (new). The barrel has the serial number, proof marks, and the date code, and the caliber nomenclature. (all new) Finish is all high gloss rust bluing. The front and rear sights are ERA recknagel, as is the saddle and pivot mount insert. The barrel band appears to be recknagel also. The trigger breaks at maybe 16-20 ounces. (exceptional trigger...best we have in this household). The trigger group is a modern "enclosed unit" recknagel assembly. Same for the inletted rear swivel stud. Basically, everything on the gun that I can identify a maker, the parts came from ERA recknagel with a couple items potentially being Ernst Apel EAW. The receiver appears to have a chemcial color finish. I scuffed it under the stockline and the laquer and then the chemical finish lightened. That's all I got for now. I'll play more after my son opens it tomorrow.
