I thought the same thing at first on the serial number; adding a 1 to the front end used to be a fairly common practice, but the rear ring is definitely A3.
I note it still has the '03A3 stamped floorplate and trigger guard; a quality sporterizing job would have included replacing the bottom metal with a "milled" guard and floorplate. I get the impression of a low cost job, maybe done by someone just starting in the gunsmith business and practicing on the customers' rifles. Still, if it is to one's taste...
