I don't think anyone was saying you could buy a new English one. Be that as it may, most, here, would take the used English sidelock at 15 large before a Spanish sidelock that was new, at the same price.
I might be wrong on that, but, I doubt it. I'm not up for either, but, can say I wouldn't consider anything English or Spanish with a single trigger.
At any price.

Best,
Ted
