Sorry, it's just another sporterized K98k
It is a Mauser K98k that has been thoroughly sporterized, ruining any collector value.
The WaA stamp was associated with Mauserwerke Oberndorf, from 1935-39, and Waffenwerk Brünn (the German for Brno) from 1940-45. The sporterized stock is a laminated model, indicating later production, so it is probably a Brno-made rifle.
The barrel is an original stepped barrel, but the original foresight assembly seems to have been removed or at least altered. The receiver has been altered for the rear mounting for the scope.
Something does not look right - I cannot see a front mounting on the barrel ring. I guess there was a front mounting between the foresight and the barrel ring - it that a flat base soldered onto the barrel? Is that scope supposed to be mounted on that rifle - I do not see any mountings on the scope itself?
A pity, because of the crisp stamps, but this just looks like a typical postwar sporterization. It would be possible to find replacement wood and return the foresight to original configuration, but it is not possible to "undrill" the receiver. I know nothing of values where you live, but sporterized Mausers are commonplace here. Inasmuch as it is a good shooter, leave it as it is. The scope itself might be interesting to collectors of such items - more interesting than an irreversibly altered rifle! How about some details?
