Well. that point has been cleared. The conversion was not done by a gunsmith in Germany. The barrel and receiver ring are marked with the British nitro proof (BNP) and the caliber. The finish appears to show bluing over rust pits.
My guess at present: a beater 98 that was rebarreled to make use of the action. Scope looks good, for its age, and is in much better condition than the pitted action. So IMOH most definitely never a sniper, just a good scope fitted to a run-down 98 that was sporterized, and rebarreled by heaven knows who in the UK. If it shoots well, be happy and leave it as it is. Collector value of the rifle is nil. But the scope would be worth 3-4 hundred over here, if the optics are still good.
