Thomas, do you plan to shoot this gun? The reason I'm asking is I have a Parker back action gun from the same period with decarbonized steel barrels.
If you shoot yours, please post your results and what shell/load you used.
Congrats on your new find. It is indeed a dandy!

David: I don't know when but will shoot it probably just to take some type of upland game and then put it away and use my hunting Parkers after that. Thomas

Thomas: when you measure the dimensions of the case please post them so I can try to make a similar case.

Carl: I will do my best to post them in a couple days. Thanks Thomas

I have been advised to not shoot Decarbonize and Steel barrels. I have a back action too and that was the advice I heard from Drew Hause who should know.

Mills: I would think that this gun has been shot before. What was the reason he gave. Thomas

Decarbonized Steel are likely the weakest steel used on Parker shotguns.

Has anyone on this forum ever blew up a set of barrels with Decarbonated steel and if so I would like to see the pictures. I believe you but I just would like to see the proof. Thanks Thomas

I think an equally appropriate question would be "Has anyone on this forum ever fired a Parker with Decarbonated Steel barrels?"

Don't get me wrong Thomas - you have a super nice Parker there that a lot of people would love to have in their collections. I'm not criticizing the gun at all.
