CA78 production year??

[Racer233]

I have a 305 Dream basket case. The neat thing about it is the hard bags. I cannot identify the year. The Honda model book is not much help. Based on the tank shape, I'm guessing 1963 or later.
The engine number is CA77E-1024412. The frame number is CA78-1024386. Thanks!!

Based upon info that I've seen it's between a 1965 and 1967. The CA77E engine started with CA77E-1000001 in 1965 and the numbers went up incrementally through 1967.
