I saw this on Ebay today and it's only the third one I know of. I've got one and so does a fellow HAMB'er. It says it was made by Ralph Ridgeway. I found a little thing on the net that said he made these for drag cars in the 60's and maybe for a Norwood Chevrolet drag car? I'd love to know more about this guy and what all he made. I got the whole motor from mine and both tops and it's neat stuff but I can't find ANYTHING else on this guy. Anyone have scoop?
