'64 Not-Plymouth Valiant Signet 200

But I'm also not clear on the production cycles where modern vehicles, current model year gets released the year prior. This is a Calendar Year chart not a model year chart and I don't know if there's someone more understanding of the Canadian production lore? I got that chart from someone who was nice enough to go down to the Windsor Public Library and take some photos of materials I was interested in.
The US production starts August 1'st. Interesting the low numbers for August. The last few 64's produced before the 65's rolled out.
