This one is a big unknown, and we are looking for more information. This item came up for sale online and was purchased by a collector. We would definitely like to find an example to document in the museum.
Was this yo-yo made by the Flores Yo-Yo company from the USA, owned by Pedro Flores, or was it "another" Flores company. When was it made? Were these made and sold in Germany only? Other tin whistlers date from the 30s thru the 70s, so it is hard to estimate the date. The pattern is similar to several Duncan Tin Whistlers from the 30s. A beautiful and unique item, but truly a big mystery to us ...
