Where do I start. I hate to be the bearer of bad news... Not sure if you purchased it thinking its all matching German original, rc or whatever.... but this rifle appears to be a hump/renumbered job. The bolt parts have clearly been scrubbed/grinded, renumbered to match the receiver and touched up with what appears to be a bad cold blue touch up. Do you see the absence of the "f" serial suffix on the bolt root that is on your receiver? That same suffix "f" would be on the top of your bolt root right below the serial number if it was a wartime model. Its not there because a font that looks like that is not even remotely available to humpers, unlike number stamp sets which can look pretty close to original looking. The floorplate has been x'd out and also stamped renumbered IMO. The soviets usually electropenciled parts to be "force matched" on rc k98ks. The only x'd out numbers on legit k98k's that Ive seen are depot reworks and post war reworks and this doesnt appear to be that, especially since the eagles are peened in soviet fashion. You have a vz24 front sight hood installed as well which is incorrect for a k98k. To me it looks like someone tried to "pretty up" a peened rc with some scrubbing/renumbering, touching up, qnw triggerguard (unless it won the soviet lottery), putting some late war bands, adding a post was czech stock.....
The stock is interesting though. Most likely a czech post war stock unless its a bcd KM. Could you post up a pic of the right side of the buttstock and of the bolt cutout in the stock? Also any marking on the bottom of the stock near the heel? Any marking on the right side? Maybe its a post war rework, I know barely anything about them.
Now comes the question of what you were told when you purchased it. If you were told and paid good money for a mostly matching German wartime example I would strongly urge you to get your moeny back. If you purchased it as a legit RC "from the importer" example then I would suggest you get your money back cuz its not an RC. If you bought it as shooter and paid a shooter price for it then its all good IMO....
