RT Journet London Vintage Handheld "Geometrical" Dexterity Puzzle model plane propeller I would think they wereGreat graphics on this one, and I'm a sucker for geometrical shapes (I can never find geometrical solid blocks anymore, but this dexterity puzzle reminds me of them.) Produced by RT Journet London c. 1920s or so I believe. It's a challenge, but I do believe achievable! Perhaps just the right gift for one's favorite math teacher who needs distracting! 5" x 4 1 8" x 3 4". Good condition with light general wear and age.
