Someone I know has one of these entry-level Spanish (I think) 12 ga. doubles. Looks like a Zabala Hermanos product to me, but does anyone know for sure? (Doesn't have an Zabala marking on it.). We can't also seem to find a date-of-proof code on it; looked on barrel flats and water table. What are other likely places to look? And while I'm buggin' you, does the 12-76 marking on the water table refer to guage and chamber length, as I think, or is it the mfr. date?
