Never seen one before but I picked up in Wally World this AM a..... Mine is'nt as fancy, the wood is all one colour, the liter tan, and the fenders hood are painted white. Also no silver paint on the head lites or grill.
I got one similar to that in orange when I was a kid. It was part of the line that allowed you to adjust the height of the rear axle. I'll take some pics of it tonight.
That my friend was a 40 ford woody your talking about. I had it, and ended up with another one last summer at a swap meet....minus the adjustable rear end.
I had a funny feeling that you'd know exactly which one I was talking about FT. Well done! ...here's the pics anyway.
