I'm going to disagree. The simple fact is fewer hunting licenses are sold every year. Fewer people hunt, fewer people buy guns, (save pistols and black guns, and that well should dry up sooner, rather than later) and everyone who wants an entry level, or better, Spanish gun can be well served by the secondary market, especially in 12 gauge.
I don't see it. My humble (and free) opinion is there exist too many Spanish makers, now, and demand won't go up when there are fewer of them. Europe is a mess, and when the full weight of the fiscal policies of the last 6 years begin to bear down on the feeble economy in the US, we will be in the same shape. I fear that what is coming down the road here in the US will make the Japanese "lost decade" look like a picnic in the park. It won't matter one bit what a Spanish gun's price went up to, when the US dollar is worth nothing.
Good luck.
Best,
Ted
