The older Expresses are more desirable than the new issue. I suspect you have a Birch stock and there is noting wrong with that. I still have mine and provides great service. Is your a Magnum or 2-3/4"?

It's entirely your call but I too would ask this question. You can always find a used barrel cheap, especially in a fixed choke. ...
Be Safe !!!
