I have had this CE 43 k-98 for many years but I have never known what the receiver marking of 35 means. It is a vet bring back and all matching. Please let me know if you have any knowledge of the meaning of this marking.
Nice K98k. I do not have a clear answer for you, but I do have a possible 'lead'.
I have seen the "35" marking before on Walther produced P38's. The '35' marking is seen on Walther produced P38's from very early to late. 1940-1945. Its been discussed on the P38 collecters forum several times.
Not sure if other manufacturers used that marking.
Here is a link to that forum. They are a bunch of great guys over there, so dont hesitate to ask.
