Supply has to play a factor in this, does it not? As OWD pointed out, new H&Ws effectively can no longer be ordered, and Peter Nelson, David McKay Brown, Peter Hofer will all (sadly) one day cease making guns. That has to play a factor in their "investment" value as opposed to Purdey and H&H which will ostensibly continue to produce guns (even if at a relatively small volume).

Dig - your depreciation rate for those Purdeys is interesting. While they certainly take a hit on resale, a "typical" modern sxs (eg AyA No. 2, Merkel 1620 or for that matter even an RBL) doesn't depreciate 50-60%.

Such a long, long time to be gone, and a short time to be there.
