Without a trade name, it's going to be hard to distinguish this Eibar, Spain .25 cal. clone from the others imported here before the '68 gun ban. They were all loosely based on the FN Model 1906 and Colt 1908 (minus the grip safety) and quality was all over the map. If you ever attend a well manned gun show, you can probably locate a 1908 magazine. Take your gun with you and try it in your gun. Who knows, it may work.
