The price you quote is about right! However let me clear up something here. The new William Douglas is just as good or better than the old ones! The old so-called "IN-HOUSE" rifles were not made on their own actions either, in most cases. Most barrel blanks were made by Krupp in Germany, and most actions were either Webley, or Anson&Deeley. The factories only assembled,by final fitting, and finished the rifles. Shotguns are made on the same actions that rifles are made on, they are simply heat-treated differently.

The 470NE chambering is worth a premium, and, if tight, the rifle you are talking about, is worth the price.
