NO IT'S NOT A 40, OR A 41. It is a 46,7 or 8 i have one , a sedan, the dash tells it.....and the so does the hood, on a 39, 40 the curve over the fender is tighter, not so straight, look at the previous pic of same car from rear seat angle, the dash gives it away.
I remember this, according to the comments from the previous picture of this same car from a different angle, it's a 48 Ford Woody. (Or was it a 47 Woody?)
