Not sure if I'm the "Ray" you are referring to or not; either way, I wouldn't know...I'm not a Bugeye guy. Had one, but it was a vintage race car...certainly not concours.
I do have a '73 Midget that I showed in Concours at MG2006; hadn't planned to...heck, I'd never even been to a show that had a Concours designation...but received an invitation by the Coucours Chairman of NAMGBR, Paul Hanley, so I thought, "why not"?
It was not as much fun as a regular show because you have to sit right there with the car...all day. Three teams of two judges, each with their "book"...which brings us back to the subject at hand. They used the Horler book, "Original Sprite & Midget". It's available on Ebay or from Amazon.
