If you were to purchase a Spanish double in Spain, you'd spend more there than if you were to buy from a dealer/importer here in the states.

There's a discussion on the "Spanish Gun" forum of Shotgunworld.com all about it.

I recently purchased a used AYA #56. If I were to custom order the gun here, it would cost about $18000. If I were to order it in Spain, it would cost about $21000.
