Looks like American skirting leather to me. The light/dark streaks could be from abrasion, as oil will penetrate more where the scratches and scuffs are. The edges are nicely beveled. Aside from what little detail I can see of the stamping on the stirrup, none of that photo looks like cheap to me. But I don't know that brand, and their web site doesn't really give any details about whose saddle trees they use or whether the saddles are actually USA-made.
