What is the value of a Western Field Shot Gun model M149?

I just paid $250.00 for one from a firearms shop in Albuquerque NM, (ron Andersons) that is very knowledgable in all things fdirearms-related. The shotgun is in Excelland condition, with poly-choke, good bluing, and nice checkering on the slide-stock and grip areas. I feel that $250 was a good price, and will not hesitate to shop and but at Ron's again.
