Wow, I learned something new. I was always told the straight drop 4” wheels were 40 only, the slant drop 4” wheels were made in 41, and post war they were all 4.5” wheels. I can agree that there was probably a little overlap to use up old stock, but I never would have guessed that they didn’t really use the 4.5” in earnest til 47.
