The socket in the third photo (PWA 1075-8) is part of a valve adjusting tool for Pratt & Whitney aircraft engines. It was common during WWII, and many of these tools are offered on Ebay under the -1075 and -23354 part numbers. The socket is detachable from the handle of the tool, which contains a straight screwdriver bit to adjust the valve lash, while the socket is used to tighten the lock nut.

Thanks. The socket does not match the set so you solved that question.

Here's one I made an offer on ebay for. Ratchet still works, sockets in nice shape, not bad for a 100 year old tool set.
