Couple horseflies in your yogurt there, Larry. One, is, you can't get a nice, new 700 built to order. Yes, there are English boxlocks available new, but, you can arm your 4 man hunting camp with Spanish boxlocks for the price of one. Two, the Spanish design might be a copy, but, it can be had with some improvements, disc set strikers being a HUGE improvement over integral striker/tumblers, for us mere mortals who don't rent our basements out to a skilled gunsmith, anyway. I've seen two good English guns sidelined for months over broken strikers. I have been told there exist 700s with disc set strikers, but, I've never seen one.
I've seen them on a 500. Yes it was light, and had a 2 1/2" level of proof. And, it was really old, too. A few of us have moved on from our frail, old, lightly proofed, but, still expensive, gun phase.
You can specify some nice options on a Spanish boxlock, self opening (not my cup of tea) hidden third fastener, steel shot proof, 3" proof, second set of barrels, fitted case, whatever you are willing to pay for. A used 700 is a nice gun, but, they ain't free, and you can get a lot closer to bespoke out of Spain, for realistic money.
Until someone very knowledgable, who is from Spain, tells me there were no companies building guns there, prior to WWI, I am going to believe the Spaniards did have an arms industry. I doubt the queen of Spain sent Christopher Columbus to England for armament for his first big adventure, after all. Civilian arms production would grow quite comfortably out of military production.
