I inherited a gun from my great uncle a couple of years back and have been using it with great success--the only thing is I know nothing about the gun and I've asked a couple of my gun-savvy friends and none of them no anything about it. I was wondering if anyone had any information about the gun.

On the barrel is printed: "THE COLT '57" - CAL. .30-06 and COLT'S PT. F.A. MFG. Co. HARTFORD CT. USA

Thanks!
