HI ,I’m looking at a Merkel 360el with a four digit date of 1041 and can’t seem to figure it out. The gun looks new, new Merkel case ,clean fresh paper work.This gun looks too pristine to be October of 41. Funny thing is it’s on the bottom rib and not the flats. The gun does not have the gold el on the opener but is engraved on the top rib either. What can to tell me ? TIA
