Three old vintage (1960s?) Litho Friction Tin Toy Turtles or Lady Bugs. Green with yellow, red and black patterned shell.

One is slightly larger than the other two with bigger wheels. See pictures. All have same pat number, logo and Made in Japan on shell.

The letter "K" in a diamond logo, with the lines forming the diamond are extended where they intersect.= Koyo / Koyo Kinzoku.

Wheels all turn by hand and friction system works.

Larger one in great working condition. Smaller ones seem to work then get stuck then start working again.

On one of the smaller ones the wheels are sunken into toy so doesn't roll on wheels.
