bigboyga,
Your rifle was manufactured in 1948. But to give you some idea of its value I need to have some idea of its condition. Please read this post of mine to give some idea of how I look at rifles. Then send me a detailed description or much better some good photos of it. Then I can give you something besides a range of someplace between $200 and $2000.
