The hood is actually all clear plastic (Plexiglass, I believe). It was used for the introductionn of the new Rocket engine in 1949. Im sure that dealers used the hoods for the 50 cars, too. I remember them when those cars were in the showrooms. Im quite sure that the plex part was not an insert, but I could be wrong
The hood is painted in body color, with a section in the center left transparent. You might contact the National Antique Olds Club and ask the newsletter editor, Clay Mollman, what he might think its worth. My recollection is: plenty. If the guy is going to put it on the Bay, hed be well advised to not make too high a reserve. If its going to be bid high, he could start with one dollar, and it would be bid up to the proper value, anyway. All too often, too high a reserve or opening bid stalls bidding to none at all. Ive seen a lot of it.
