Well, I just bought a Half Red Half Black Duncan O Boy and was wondering, when was it made? Doesnt have to be exact, but I just wanted to know when. I know the mint colored one was the first (Well, I’m pretty sure) but I have no clue as to when the BlackRed one was made.
The first O-Boy was just a rebranded Flores made of existing Flores stock in 1930. The Duncan O-Boy that you have is a beginner-type yoyo, sold with a pegged string, that was manufactured in the late 30s / early 40s.
