Does anyone know WHEN New Era started making 'Cooperstown Collection' or 'Throwback' hats?

This might throw a monkey wrench into the works, but I just picked up a New Era with tagging that matches on the chart to the PRE 1983, but NOT to the 1950 one listed but the hat is a 1940-1945 style St Louis Browns:









Did the Orioles ever do a Turn Back the Clock style using St Louis Browns?

The wool looks right for the age - including 'rust' type spots that I have seen on vintage wool jerseys but not on newer wool caps. Also, the piping down the crown seams isn't perfectly centered and the vent grommets aren't perfectly stitched like you see in newer and throwback style caps.

Thoughts???

All the best -
