That was my first thought too Tom...but then the new Revell Oldsmobile parts probably wouldn't work (without modification) with the resin JF body, which I'm sure is based off of the AMT '51 and Revell 53/54 Sedan Delivery. Also if you wanted to keep the fancy Olds trim, it would have to be duplicated onto the JF body.
Yes Al, this is the same car I have pictured in my post...but I haven't seen anywhere that it's a documented, GM factory built Oldsmobile. There are actually a few of these out there on the interweb, but I could NOT find any old factory photos or literature from back then supporting a GM assembled car I believe all of the images found in a search are built from Chevrolets...
