Ted, my lightweight ten AYA is sure enough not marked "Matador" anywhere on it but they were marketed in the Matador era. They are a wonderful, good looking, good handling ejector gun and are full 3 1/2" chambered magnums. Thankfully, they are double trigger guns. They are just lighter than the blue frame tens. When I have a chance, I will try to find out when they were sold and how they were described. They are well fitted, mine is not broken in, still drags on the hinge, so long term reliability should not be a problem. My Dad's 12 gauge Matador broke in fairly early but never developed any sign of looseness.
