Fox/Savage side by side info.

I have a 12 GA Savage /Fox double barrel shotgun that I cannot find anything about. It has 30" either chrome or stainless steel barrels and trigger guard. Blued receiver with - M O and a G in a circle on the inside of the reciever. It has mild checkering on the forend and the pistol grip. The pistol grip also has a plastic plate on the bottom. On the barrels there is the standard = FOX Savage arms corporation, Chicopee falls Mass. usa MODEL B on the Left barrel. Proof Tested 2 3/4 inch chamber 12 GUAGE. On the right barrell. On the receiver is the fancy scroll work with FOX in the middle on both sides. The bottom has fancy scroll scene of 2 ducks rising off the water. But I have never seen one with the chrome barrels and trigger guard. Any information will be greatly accepted. I can find alot about them with blued barrels but nothing about mine. Can anyone help with this?
