The gun is a copy of the Sako Finnbear. I had one. It is a good gun. The value is about $450-650 depending on condition. Get the serial number checked as there was a recall on Howa because there was a flaw that caused the gun to fire when the bolt was closed.
Dickson was just the importer I believe. Howa is made in Japan. Same as the Smith and Wesson Model 1500.
$4000.? Never.
