Rook:
The original poster proposed getting into British guns for under $3000 that would at least hold their value, or perhaps gain in value, over time. That excludes the top London marques. Birmingham guns, by the best craftsmen there, were made to virtually the same levels, but can be had for much less on average. As time goes by, ("play it again, Sam") there is also a good chance that these fine Birmingham products will gain in stature as well as value. Hence no or little loss.

You can buy a Bond Street suit and know you have the best. But a London tailor who moves to north Birmingham loses none of his skill, but must accordingly charge less for his wares. Still, the suit fits just as well, and is equally well made.
