Nice gun, well done.
It's not actually a 'navy', it's a 6" and the only reason is that they couldn't get the 4" going at first
Judging from the serial number it was made at around 1973, can't read enough of the number to be more specific. The pistol still has the Swiss style frame, which was being phased out in late 1972, early 1973. Nice to see it still has all whistles and bells with it. Keep it safe and complete
