If you sell your gun out of state, it must go to a ffl dealer.
Your gun is a dash 2, there was a dash 1 and a no dash (modle 52). The comment that there are less than a thousand made is incorrect.
I have purchased a -1 for $600, and a -2 for $800, I would not sell either of these guns for what I paid for them. These would probably sell for $900-1250. With you not having the original barrel, who knows...the original box, documents, barrel tool all help with the value. Check Gun Broker for current value trends.
If you live in my neck of the country (Indiana) I would help you sell it. I do not have any interest in it (but would like a 52 no dash).
Good luck.
