Sammy's Charcoal Grill Salad Dressing

Sammy's Charcoal Grill was a locally owned restaurant which was in business here from the early 1950's through the 1970's. Their steaks were outstanding. They were well known for their wedge lettuce salad which was covered with a generous serving of their special salad dressing. I have searched for their salad dressing recipe for years and finally found someone who had it. I'm putting it here for safe keeping so I won't lose it!
