If the rifle doesn't say G29/40 or WZ 29/40 (with the WZ struck out) on the left side of the receiver, the rifle is a Styer K98 made with a recycled WZ29 Radom receiver.
Simply the receiver was made and the rifle was not assembled before the German invasion of Poland (start of WWII). The Germans sent the captured parts to Austria for final assembly.
The rifle is nice but something's are not WWII correct (miss-matched parts or refurbished at some point).
The receiver is Polish (Radom with Polish eagle) but has the Styer 660 code.
The right side of the receiver has the 3 x waffen amts 623 (Styer correct - these are inspection stamps indicating receiver assembly, final assembly and shooting test approved) and 1 x Polish inspector stamp.
The left side of the receiver has the Reich's Eagle (Nazi Ownership) and serial 3251 'a' (could be 'q' but more likely 'a' suffix). If 'a' this indicated the first or second month of production 1940.
The barrel is of German manufacture and is marked 7,92 (8mm Mauser chambering) and has a contractor code, lot number and year of production.
The right side of the barrel has three additional waffen amts 623 (Styer correct - indicating receiver assembly, final assembly and shooting test approved)
The left side of the barrel (matching to the receiver) is Reich eagle marked and has the same serial as the recover.
The rear sight also appears to have a 623? waffen amt which means it is matching to the rifle.
The sling appears to be original (not enough pics).
The rifle has worn blueing but a nice authentic patina.
What is not correct is the front and rear band (serials do not match the receiver/barrel and are the incorrect type for the year of assembly). The Germans used three different types of bands (milled 'H' type, speed milled and stamped) and these bands are stamped (generally found on 1944 and 1945 rifles). If the receiver/barrel didn't have the three proof marks, this could be correct but those proof marks show that the rifle was assembled before mid-1941 when the Germans started using the first of several shortcuts in K98 production, including less inspections stamps to save time (cupped vs flat butt plate, 12 inch vs 10 inch cleaning rod, laminated vs whole wood stock) etc.
The rifle also has a cupped butt plate (not correct for 1940 - used 1941-45 adoption year occurred at different times for different factories) and is red glue laminate. There were some laminated stocks with flat butt plates, but one reason they moved to a cupped butt plate was because of delaminazation.
The cleaning rod is missing and due to the year of manufacture it probably didn't have a sight hood (sight hoods introduced in 1941).
The trigger guard and floor plate also looks like they may be stamped (not correct for 1940), not clear enough pics.
I don't know if the bolt is matching to the rifle or not (I assume that the bolt will probably have two-three different serial numbers).
The finish, mixture of parts indicates to me that the rifle is maybe a French refurbishment which would have been done right after the war, explaining 65+ years of patina on a miss-matched rifle. I owned a bnz (also Styer) marked rifle which was French refurbished and looked almost identical (m/m parts, finish and patina). I wouldn't be surprised if you had an 'R' marked on the butt stock somewhere. If not French, probably a very early post-war re-furb. This rifle was more than likely imported in the 1950's-70's commercially.

Most similar examples I have seen were actually Norwegian Refurbs. Sent from Styer to Norway for German use, left in Norway once the Germans left and later re-chambered to 30-06. I found at least three examples of such a rifle on the internet. I think this might also support Waffen SS use, Styer had many connections with the SS and several SS Divisions were based in Norway. This is only my inference however and I have hear say documentation to support this theory.
