8 to 10 years ago these were around for between $175 and $225. Wrapped in greasy newspaper and all matching, with no9 bayonet. Now a short decade later they easily sell for $600-800, a return of 300% or so. Try and get that out of the stock market, or investments. Apparently, the events of 2001 did not effect the resale of rifles kept in collectable condition.
Same rifle, once shot a few times, drops drastically to the $400 range. I have bought a few of the no4mk2s from the mummy serial range, sporterised for much less than their original market price of $175.
There are plenty of rifles which have been shot out there, and the occasional owner makes another one every now and then. But an unfired rifle is something to brag about, and even the method of packaging it, in those 1950s newspapers with grease, is something for discussion. In todays world of arms restrictions, there are unlikely to be many more releases of new in the wrap Enfields from military warehouses.
