Help needed to identify year of Yanagisawa

[eve1973]

I am thinking on selling an old Yanagisawa saxophone but would like to know more details about it. Round the bell it is engraved Continental then has the numbers near to the bottom 500 3367347 made in Japan

Any help would be appreciated to know the year, history and how much its roughly worth

Thanks
Eve
