Denny:I think that the second picture is the primer going on not the color coat I think that's bare metal over the door and in the back sail area. And I agree that the intieror was painted first and I'm guessing they had templates made to go over the window openings and they masking taped the doors and door opening or had canves cut to the openings and taped them into place(any way that's the way I'm going to do it).Now on my 52 out of Baltimore there was gray primer on the insides of the doors and behind the seat could it be that different plants use different paints. And this was war years could the red oxide been in short supply ( just thinking out loud).If you have any input on painting the interior I could use it.
