To my knowledge, many of the years have the exact same colors, but are named differently each year. I personally call it Forestor Green or "simply" Utility Green.
Here is the color I have for my 1952.
Juniper Green
It is a PPG Acrylic Enamel I bought years ago.

This is one quart.
On my current 1960 project, I had some spray tests with new paints. The same color that I had tested came out completely different from each other and required a different number of coats to cover. For this testing, I went to my local auto paint jobber and looked in his old color chip books that he had. I also ordered an original chip card for my year truck from Ebay so I had one for myself and always started with that chip card to be consistent with different brands.
I hope this helps.
Good luck.
