Actually, the early medallions had a red eagle, silver outside. After the death of Alex Sturm, Bill had the eagle changed to black. (1951)
So from 1951 until the 1970's era,, the medallion eagles were black, recessed, and silver outside. Then, the background was black, the eagle was raised & silver. The MKII's were that way, until later, they introduced the raised silver eagles,, with a red BACKGROUND. So, the MKII's never had red eagles,, except for a "one of" special guns.
So, no MKII's in regular production had red eagles.
