It makes no difference how old any firearm is if it does the job.
I have no idea how old my 1100 is. I got it in a trade from a fella who said he bought it new. The shotgun is 2 3/4" chambered without
screw-in chokes. It does the job I expect. I killed a 15lb gobbler this past spring.
GOOD LUCK and GOOD SHOOTING!!!
