Thank you Kuduae, for a very informative and sensible reply. What you write makes a lot of sense. We had the same problem here in Norway for a 5 year period where private guns was completely banned, and those who hided one would be punished by death. A large number was still hidden in very unfavorable locations and the result was often rust. Luckily quite a large portion of all private guns that was confiscated in 1940 was returned to its original owner shortly after the war ended. The result is that we still have quite a few old guns laying around in Norway.
