If I recall correctly, there was discussion about Singer making these up for the 1951 centennial and using them on machines made in advance (for shelf stock) and even on machines made through 1953 to us up the stock and to ride the "buy them because they are special" wave.
If I come across which group (may be antique singer YH group) was having the discussion, I will point you at them. They would appreciate a 1950 "centennial"
