After Duncan bought the Flores Yo-Yo Company, their first models were very close to the Flores design. The first Duncan was the O-Boy. While mentioning the patent on their "Yo-Yo", the first O-Boys did not include the Duncan name.
Pictured here is a mint original O-Boy, so similar in design to the Flores company yo-yos, that perhaps Flores blanks were used in the early production. Super narrow gap, but with slip string. Ink pad stamped logo, just like some of the original Flores models.
