Tinkertoy Skateboard and Rider
I have no idea what the date is on this set. It’s #191, and still a Questor/Child Guidance company. Playschool bought them in 1985. The packaging on this looks like some sets from the late 70s. The one I have does not actually have enough pieces to build a skateboard or anything else, so I essentially bought a container for 3 bucks.
UPDATE: Added some pics of more complete set with instructions from Ebay.
