FWIW, on Midway’s Optics drop-down, “Gloss” is not a choice under Finish. Same on the Leupold site. You might pose this question to Doug from Cameraland, but I think dale06 is probably correct. You can look on GB, Ebay, etc, but if making it all pretty is the goal, I suggest you check one of the sites that specializes in vintage models. You’ll pay a pretty penny for a pristine one, but if your rifle has a few blemishes, you could match it with a similarly worn scope.
I paid about $200 for a pretty nice M8 4X to go on an old custom FN last year and think I did pretty well. Not quite a perfect age match, but close enough.
Good luck.
