For the "republican" Spanish forces (actually a mix of factions from the left, including real liberals and separatist elements - essentially the worst elements supported by Liberals and separatist factions); there are a great many moving parts to the SCW but basically the government (parliament) was highjacked by the left, in the national socialist of Germany style (locking out the SPD from parliament) and highjacking the republic (the Spanish republic was as illegal as Hitler's seizure- both blocked opposition parties)Yours is a Polish K98 that was sold to Spain for their Civil war.
