Recently bought an old tool box at an estate sale. The photos are of several tools that I have no idea what they are or what they may be used for. Can any one tell me what the tools are and how they are used?

Thanks.

The picture on the left is 2 parts of what would come as a combination square. What's shown is the center head and the protactor head, there would also be a 90/45 degree head. The rectangular piece with the small scale is a depth gauge. The photo on the right are spanners typically use to adjust mircometers.

The ruler and attachments on the left are known as a combination square. Google and you'll see how to assemble them together. The bottom one is not quite right. Useful for marking square, or with the protractor part, angles on wood, metal, etc. I'm not sure about the thing in the middle. Some sort of gauge, I guess.

The spanners on the right are for adjusting sleeves and such, like adjustable spring self closing hinges for screen doors. The pin at the 1-1/4 mark on the rule would go into a small hole in the sleeve, and is pryed in a clockwise motion.
