Also, perhaps this has been answered before,
Why is it that, in the movie, the main gray always appears a soft blue color, but every gray/blue vest or jacket that can be found (like jonny's) is straight-up just a monochrome gray with barely a hint of the indigo. I speculate that the one MJF wears is an earlier run, which is why it has more attributes of the later 1983-style half-and-half jackets (like the one you sold me, Mitas), with the 2-segment band and the bluer gray, as opposed to a 3-band and monochrome gray like the 1985 zip pocket jackets.
Maybe it's just me being crazy, though.
Edit: It's probably just differences in lighting and filters, and I AM crazy. Also, the attached photo of my jacket is not a good example.
