Where were only 47000 plus change of them made. They were made from 1935 to 1957. I have a 3-digit serial number gun that I paid $600 for MANY years ago. Long tang, standard grade to which I added the bolt peep. They are a fairly heavy gun, which was one of their drawbacks, but extremely well made. A LOT of these guns went to Canada and Alaska for bear work. Their prices have skyrocketed over the past few years. I still see ammo available for them, but a bit on the pricey side. You can usually find it at gunshows, and only costs a small wheelbarrow load of cash.
All in all, they are quite collectable, and are sought after by many. If you ever get a chance to pick one up at a reasonable price, I would recommend it.
