765. Flexible allen wrench to adjust the points on GM vehicles with a window in the distributor cap.

766.

It was probably mounted on one of the massive fire doors in the heavy-timbered warehouses used in the 1800s and the early 1900s. Modern versions can be seen here.

767. Usually the wood is steamed and then compressed or bent to make an impossible object, or just soaking the wood can also work.
