Dating my Receiver

Is anyone familiar with a way I can date my Yamaha CR-620 receiver? I know is was made from 77-79, but am trying to nail down the year. I haven't been able to find any database that goes by serial # etc.
(By dating I dont mean being becoming involved...I really like it a lot but..... we're just friends ;-)

I don't believe Yamaha kept precise manufacture records so I don't think you will ever be able to figure out the exact date it was built.
