I have recently purchased a Browning A-5 Light 12 from a friend. It is still in the box and never been shot. I dated the gun from Brownings website to 1977. It is in Immaculate condition. I have found around 1976 they moved production to Japan. The original box shows the gun was made in Japan,However, the Barrel indicates it was made in Belgium and Also has St. Louis, Mo. on it as well. There is a # on the Barrel but it doesn't appear to be the serial #. Should these #'s match? In addittion, The receiver serial # and the box serial # match. I was a little confused on this. Is it possible the barrel was made in Belgium and the reciever in Japan? Thanks for your input in advance.
