Jimbo,
My 57 had the bottom left bird on this page:
http://www.oldgmctrucks.com/page0288.html At first, I thought it just someone goofing around but then I realized the situation.
My dad and I bought the truck at auction from the county. They had used this truck to pull behind their gravel graders so the grader operator had some way of getting back into town at the end of the day.
So there's no way they would have pimped that out with a hood bird from something else. It was a truck that got whipped mercilessly.
Here's two of the three grader trucks we got at auction. The '57 with the hood bird isn't in this photo. Sorry.
