The Marlin Model 62 "Levermatic " rifle in caliber .256 Win. Magnum was only made from 1963-1966, with about 9000 made. These are fairly scarce- I have only held one of them in my life. You MAY find one through on line gun auctions, such as gunbroker.com, or auctionarms.com. Your next question will be where you will find .256 Win Mag ammo. Do not believe this is being commercially loaded.
Should be on the barrel near the receiver.

This can be accomplished by providing the serial number to your Marlin model 1895 lever action 45-70 chambered rifle.
I can't find any indication that they made a 30-06 lever action. I can't find any indication that they made a 30-06 lever action.
I cannot find any reference to marlin ever making a model 226.
On line auctions.
Start with the markings on the gun. Is it a Winchester,Marlin,Remington,etc? What cartridge does the rifle fire? (.22,.243,30-06,30-30,8mm Mauser?) Is it single shot or magazine fed? Is it bolt action, lever action, semi-auto? When you can answer these questions, you can get an idea of when and where it was made.

I was told to subtract the first two digits of serial # by 2000. My gun starts with 25, so I'm assuming if the guy is right, my gun was made in 1975.
You really need to find a factory trained gunsmith.
