I just bought a new Bulldog case for my 336 straight lever action gun, cal 30-30 win. which has a Leopold 4X scope and a sling. Looking for a serial number so I can trace the date of manufacture, I found a number just behind the trigger. It is 2002xxxx. Does this correspond to a manufacture date of 1982? That would be about right. I got it brand new from a dealer in PA around that time. I had to get a form from my local sheriff's office here in Ohio so I could buy this gun in PA. I wish I had some of the original documentation. About 20 years ago, my brother took this gun deer hunting in W. Va and that's the only time it has been used. I fired half a box of ammo through it when it was brand new. There just isn't anywhere around here to shoot this noisy thing. The gun is in great condition, just a few scratches from eye glasses on the side of the stock. No metal wear or shiny spots at all. It's all original except for the scope and sling that I mentioned. I wonder if I should sell the whole outfit. I never use it. Ijust take it out of the closet and look at it sometimes when I'm watching a John Wayne western. Those rifles they toss around in the movies look like they only weigh a couple of pounds. This one of mine weighs a TON. I worry about taking it to a gun show at the fairgrounds, who can you trust?
