I happened to see
THIS Craigslist ad in my area. There was no picture of the set but I was able to get a photo from the seller. He listed it as a 1957 Admiral. He couldn't give me a chassis number but I did at least get the picture. It's a pretty neat looking Admiral set. I can't afford it at the moment with my recent purchase but thought I'd give someone else a chance to grab it if they were interested!
