But no British, nor French? Strange omissions, especially given the very clear heritage of the major designs used by current Spanish makers. Looks like you ought to be moderating an anything-but-British shotgun forum.
Cost is one good reason to buy, or not to buy--assuming equivalent quality, of course. Which might lead one to ask why one should pay more for a new Spanish boxlock, based on the same design as a Webley & Scott Model 700 . . . when one can buy a very nice used W&S for less? Why waste one's dime buying Spanish, now that prices have gone up significantly? And if one is looking for a 12ga game gun, the Brit gun will also be lighter--if that's what you're looking for. And many of them still in regular use, after half a century plus. Nothing like the pre-WWI guns, of course . . . which seem to be scarce as proverbial hens' teeth on this side of the pond. Where one can find thousands of Brit guns that have passed the century mark.
