You really gave me a chuckle with your post. I should have realized my floorboards, which are tongue and groove, probably weren't from shipping crates or someone put an awful lot of extra work into machining tongue and groove boards to use in shipping crates. So now I'm sitting here wondering how red my face is for not being aware of the obvious. But I guess when I looked at the boards and remembered as you called it the myth, I just put 2+2 together and my floorboard came from shipping crates. DOH!!!Ford has part # drawings for all floorboards, the claim of using 'shipping crates' for Model T floorboards is just a myth. The boards are constructed with tongue and groove, using solid wood laminated boards.
The boards were coated with slush black paint, very thin.
Here is an original, with sticker on it.
