I believe that current made rifles are made in the state of Maine.
Standard Vanguard is about $400. My references do not show they were made in .280 caliber.
Contact Weatherby, or the Weatherby Collectors Website. The data is not published. Sorry
The later ones are made by Howa in Japan. Vanguard is almost identical to the Howa 1500 which was also sold as Smith & Wesson rifle and Mossberg 1500.
Impossible to answer without the serial number.
There is a limited amount of information available on the Weatherby website. See link below- and you did not give us the serial number. Shame on you.
