Hi all, just a side note, the Zabala made 28ga is not made on a scaled frame to that gauge. Zabala 28's are on a 20ga frame. As been said before, Zabalas can be a crap shoot with their single triggers (like most Spanish SxS's). As skeettx said, look for the markers mark, Zabala is ZH and "Made in Spain" should be on the bbls.
Here's a couple links discussing the Marlin Smith's:
