Put mine on the leading (German) auction, Hermann Historica a few months back. There were a few other 33/40s as well and they went for an average of 750€. Price seems to depend on the condition of the wood (cracks etc), the markings, whether the numbers match (only the bolt, the action and the stock were stamped) whether it´s been re-worked in any way and whether it still has the correct sight hood. A number of these rifles have appeared during the last few years from Norway, with Norwegian
police and military stamps and this seems to have pushed prices down quite a bit. Have found that many/most of those I´ve seen have suffered from barrel erosion at the muzzle end (the flame is quite spectacular at night) and are therefore not all that accurate.
