This past weekend I was at the Rough and Tumble Engineers Museum in kinzer Pennsylvania and found some tools in the flea market. The nut drivers are Pratt-Read and look high quality. The lathe tool is a Pratt & Whitney #2 threading tool. The level is a 4.25" Starrett. I like buying interesting looking wrenches and the two big ones were pretty interesting. The main body slides up and down by cocking it a little bit and then sliding it up and down and then re-engaging it on the teeth to lock it in place the small one is not unique but it only cost me a dollar or two. I'm not sure what the small box is. It almost looks like a very tiny precision surface.
