Ok folks, there finally here! These are the Mercury plastic oval emblems used from1957 to 1962 approx. They were "decorated" in four color cominations.
The emblems were a very difficult part to reproduce, based on the painting and vacuum metalizing of the small lettering in the injected molded part. With help from a few individuals who worked on this part in 1955, to Mercury Marines legal department and the many colectors who helped finance this project through pre-production sales. Thank You!

How they were used...
Mercury traditionally was very creative in how they used componets on engines, especally during model year changes. These would be the most common applications of the emblems.
1957
A black background emblem was mounted on engines painted Sunset Orange, Bimini Green (Merchromic green metallic), Sarasota Blue.
1957-1958
A silver background with chrome and blue lettering would have been used on the blue two tone painted engines such as Sarasota Blue/Sand Tan and the Marlin Blue/Gulf Blue combinations. This emblem was also found on many Sunset Orange engines.
1958-1962+
The silver background w/light gold and red lettering was mounted on all colors during these years. Of course there were always were exceptions. The white background w/light gold and red lettering was mostly used on control boxes for the Cloud White motors.
