1953 standard cab interior color:
Sheen Gray Poly - PPG (31104; now 27467)
Sheen Gray Metallic - Dupont (202-81407)
Supposedly, in 1953 some plants continued to paint the regular cab interiors the same color as used in previous years.
What kind of 1953 truck do you have?
As posted above, the transition point between exterior and interior colors is where the outer sheet-metal "skin" ends.
