So Researcher, do you think that the chokes were changed when the gun was refinished or could they have been originally been Mod and Mod? This CEO has indeed been refinished and restocked. The CC are not right but it is a C grade 10 GA and the only 10 GA that I own. I was suspicious in that the markings are stamped instead of engraved. I do have a 12 GA CEO with 2 7/8 engraved on the barrels.
