Re activating forgotten target pistol

[Ganderite]

Thanks again for the replies all.
As a novice I am not understanding most of the abbreviations used in these replies.
12.6 guy?
The subject pistol is an H&R Sportsman, 6" barrel. I expect that is licence-able, so it would be restricted - not "prohib" [prohibited]?
I have a strong feeling that the pistol was registered in 1953/4 - and then put in a drawer. Do these records still exist?
The original owner is deceased.
Can some please explain more on the implications of the Grandfathering?
I have been told I am paranoid about all this, and I agree but I come by it honestly when dealing with bureaucracy.
I would be more than a little miffed if, because of a wrong step or opening a can of worms with questions that I can't answer, this little pistol gets confiscated and destroyed by some zealous individual after disturbing it from it's peaceful existence in a drawer somewhere. I intend to tread very carefully.
Thanks again.

A 6" revolver is easy to register. Someone with a PAL phones the 1 800 743-4000 #1 #4 #2 #2 and explains they have found an old revolver bought new an 1953 and wants to re-register it.

They will ask make, model, and serial number and name of original owner. They will give you a FRT number and refer you to another web page where you verify the make and model of the gun and then they mail you a piece of paper.

I have done this a number of times, without any difficulty.
