I just received my RC mauser k98k s/42k 1934 receiver.
The numbers are mixed matched, however, i got rifle with a striaght bolt. I thought mausers k98k had bent bolts, maybe this was the first year model so a bit different?
RC rifles are made up of mixed parts from dozens of rifles- the bolt is not original. See the pic sticky above for what an S/42 K looked like as manufactured. Most likely the only original component that is S/42 K is the barreled receiver.
