It was made August of 64 and is a convertable. Thanks for all of the great feedback ... still a great 3 screw ... now to find a 22lr cylinder. Anyone know where I can find one?
Just purchased a 1964 Magnum only serial number 399xxx in very good condition (no wear marks on the cylinder) but no box. Does anyone know what the market is like for these? How about the value? Thanks in advance.
