The 1938B was made in 1979. It is one version of about 20 different versions made over the years since 1939. Unfortunately it is not possible to give you an estimate of value without some sort of description as to the current condition of the rifle. The condition is a large part of the value. It's the same with any antique. It could be worth something or it could be junk.
