Greetings to everyone. Recently, I've come across an FN model 10/22 pistol in 7.65 cal. It has no lanyard loop, with identical black, plastic grips on both sides. The serial number is A 0XXX. On the bottom of the trigger guard and on one side of the magazine is rather crudely engraved the word Texas and a seven digit number. Can anyone broaden my rather limited knowledge about this pistol? ie. vintage, original purchaser, etc.? Thanks in advance for any all help, Gary.
