Stock Interior Sheen?

[smerkey]

Hi Folks,

Been lurking here awhile but this is my first post with question, I think.

I am doing a body-off resto of a 67 c10 longbed. I want to go bare bones, full stock, 250 ci, white trim, medium blue poly color, radio delete, etc. to match my first vehicle when I turned 16. I am to the point of laying paint on the cab and have a question: What was the sheen of the painted surfaces on the interior of the cab? My recollection is that is was less glossy than the exterior but am struggling to visualize if everything/anything inside was muted gloss, just parts, or what.

I apologize if there is a thread already here I did not find while searching but could really use some expertise. Thank you in advance!!
