Sorry I miss understood, I though you meant what was MY question. He is asking 450.
I did do a bunch of searching and could not find anything\threads with current dates. Also checked Gunbroker but with different makers, B barrels, no maker and antiques the prices seems all over the place. A lot of the Gunbroker stuff looked like it was just a matter of who was bidding, similar guns would have like a 100 or more difference.
I figured I could get a current and "normalized" version of what the value is. I am looking at keeping this gun so I guess I was also hoping to get some info on if a B barrel is a good choice.
So looks like you are thinking that would be a little high. Thanks for your reply, you have also helped me in the past and I appreciate you feedback.
