Well, the price is great but it is not gold engraved from what I see. The "gold engraving" seems to be gold rubbing in the standard engraving similar to the way that Browning Double Autos were decorated. In the case of the DA, this rubbing usually rubbed off with a little use.
Still, if the gun approaches 100% condition, it is a very good price. Especially if it has the Invector choke system.
