My AyA is Marked differently than Skeetx's. It does not have J.C. Higgins at all, just "Sears Roebuck and Co. Chicago Ill. Made in Spain" and "Model 437512371 12GA 2 3/4" shell LT-F/RT-M" all on the left barrel, nothing on the rib, and "AyA-Aguerrie & Aranzabal-Made in Spain" on the right. The lettering is in different font, and I think the Rt bbl. was done by AyA, and the left was done later?
