Hard telling when and where this rifle found an RA '03 barrel. I thuoght all of the RA barrels in early 1942 went on rifles. Not a spares barrel, by any means. I would guess a fairy recent re-barrel job. Perhaps 1-2 yeras ago? Not sure by any means. Is there large "B" stamp on the bottom of the triggerguard? If so, then a Greek rebuild. Rifle isn't the ideal shooter.
