The post WWII Marlin lever rifles are the smoothest working actions I have ever used. I have had about 5 in different calibers and styles, and I now own a 336 SC .35 Rem.
I have paid almost $300 for several of these rifles,and I think the price is a little high, but there are not too many around for sale, at least not here in South East PA. They are excellent hunting rifles, very popular with bear hunters, and they don't stay unsold very long.
I'd expect it to be in excellemt working condition, needing maybe a little blue but no parts.
As stated above, if it really rings your bell, buy it. I was looking for mine for several years before I found the right one.
Enjoy.
