Could be.
I have an early 42 ce (Sauer) with laminate stock, cupped butt plate and a front sight/muzzle protector that would not work with a hood. A swp45 just sold on the EE.
The Germans did start using sight hoods around 1941 and the front sights were slotted for their use. As with the introduction of laminated stocks and cup buttplates there were no across the board introduction dates as there were so many different manufacturers of K98's within the German Reich. I have seen pics of several original rifles dating from 1937 through 1940 that had the sight hood added during refurbishment at German repair depots.
Your rifle action was originally produced very late in the war by the serial number and lower case suffix. The Czechs used up many German marked actions post war but used upper case suffixes. An all original K98 marked SWP 45 is a hard to find rifle as the Russians overran the factory in 1945 and not many ended up in the west. They were a full kreigsmodel stock having no bayonet lug and no band spring having the barrel and sling bands simply screwed to the stock. The very last ones produced had a sheet metal rear sight that was very crude.
