If the marking on the LH side of the action is:
Gewehrfabrik Danzig ,,it is one of the sporters built at the Danzig Arsenal after the end of WW1.
These were built for a short time,,a yr or so,,before the Allied Authoritys got around to inspecting each German Govt arsenal & shut them down.
Erfurt, Amburg, Spandau all did the same thing as far as building some sporter 98's on what had been the military 98 the arsenals had been making during war time.
Just a way to keep some people employed, make some money and stay in business,,at least for a while.
The sporters got exported mainly to the USA at the time.
'Gewehrfabrik Danzig ' simply means Rifle Factory, Danzig.
Danzig was the German name for the Polish city of Gdansk where the Arsenal was located.
The other Arsenal made post war sporters sporters are also marked as to their source but in different styles of lettering.
The Erfurt Arsenal sporters for example were simply marked ' Rw E. ' (Reichswerke Erfurt) I may have spelled that wrong))
Double set triggers and 8x57mm cal are quite common.
A sporter built on a Military issue M98 made during WW1 at the Danzig Arsenal is another possibility. The Military issue rifles had their
front recv'r ring roll marked 'Danzig' with the year of mfg underneath.
MAny of these have been built into sporters over the last century both here and around the world.
An orig condition post WW1 Arsenal sporter from one of the German Arsenals in nice condition is not often seen anymore.
