Whether this rifle was made all from parts to be sent to Spain, or it just happened to have no serial numbers match and then was sent to Spain, I'm assuming that my rifle was made between 1928-1931 by Radom. The Radom stock and most likely Radom serial number leads me to believe that I have a Radom made kbk98. Those are the only markings on the receiver. I actually found a rifle that was a couple hundred numbers off, and it was made in 1928 or 1929.

I tried looking up Radom rifles made in different years and looked at their serial numbers. I have no idea what this stamp is, it could be from another country. Although, right behind the sling bar is a marking that looks like 2 triangles put together, with the points of the 2 triangles make a diamond shape. The stock is a plain kbk98 stock, it just has the bar for the sling cut out on the side. 22 LR WEIGHT 6.5 TO 8.5 LBS OVERALL LENGTH VARIES LENGTH OF MAGAZINE 2.2 Prior to World War II the Mauser factory in Oberndorf made commercial. The bolt has a polish eagle stamped on it, with another faint stamp under it which I can not identify. My rifle also has a straight bolt, either from a wz29 or an earlier made polish rifle. Nothing matches except the front sight, which is pretty odd.

Like I said, it's scrubbed, so it was sent to Spain for the Spanish Civil War, whether directly or most likely indirectly from another country. This is what I now additionally know: The stock has the dark wood dial rods through it on the barrel guard and in the bolt cut out, which the guy said Radom did to their stocks for structural strength.
