I have one of the old A-5's, it is a beautiful gun. The serial is 235,xxx. It has the last three numbers on the screw heads and the safety is an odd job in the front of the trigger guard. Round knob, made in Belgium with a St. Louis address. I do not use it any more, I am afraid that I will crack the forearm, which happened to a lot of them or scratch it. So I bought an old Savage pump to shoot. I look at the Browning and shoot the Savage. You could just buy an old Savage in good shape and use it, they can be had for less then $200 and do very well.
