1950s vintage jumbo wood beads, early Playskool bead stringing toy

Older Playskool wood beads in worn original can (no lid). Can is worn, and I don't believe this is a complete set.

Beads are as shown, the colors are different than on the 1970s vintage beads I remember. And I'm not positive that all of these beads are original to this set.

These are 1950s vintage, with Chicago 47 address. The oldest Playskool toy I've ever found, I think.
