You can buy a container of Birchwood Casey Stock Sheen and Conditioner for a few bucks and, by rubbing it into the glossy finish carefully with a soft cotton cloth, remove that high gloss and have a resulting satin sheen. I did this to a Fox a few years ago that a previous owner had "shined up" way too much. Made it look much less "garish" and a bit closer to period correct. There are other ways to do this, such as with rottenstone, etc., but this inexpensive bottle of stuff works pretty good.

Enjoy the gun, "make it yours" by shooting it often. It's stocked way too high for me, but maybe you shoot trap.(?)
