Is this a Coke or Pepsi VMC 33?

[MoonDawg]

One unique thing about your 33 is the main door is
one piece.  Most 27 and 33's had a two piece door, and
a chrome strip riveted between, just above the bottle chute, and was often used to divide the red from the white.
        This could provide more design opportunities.

These one piece doors are a little harder to find.
