Wooly Willie -- Hmmm. Maybe my memory is confused. If so, not too much as Wooly Willy had a magnetite beard so that kind of keeps this on topic.
"Wooly Willy went on to become one of the 40 most popular toys produced during the 1950 to 1980 period. It was frequently copied around the world. One set made in Japan even had "Made in Smethport, Japan." Fortunately the copiers were never willing or able to make the engineering effort to duplicate Willy's quality featurers----special magnetite powder, a sturdy anti-static plastic dome, thick display card and a strong drawing magnet."
The site is an interesting read. I recognize another one of my early toys which was on it - "The Electric Toy Set". I remember the fish.
