OV is the Parker stamp for the Trojan which is not a graded gun but rather Parker's entry level shotgun. It is every bit as solid and functional as the graded guns but lacks any of the fine engraving, checkering, nicer figured wood, ejectors, forend latch, etc. Internally, they are about all the same except for the finer filing and finishing of the internals.

Hey, it's a Parker no matter how you slice it.

If it is stamped 16 it should be a 1-Frame.

I'm glad it's not a super valuable gun, cuz I plan on shooting it at ducks :) you know how hard on equipment that game is. Thank you for your help.
