A „Measuring Wheel“
could be used for measuring the inside diameter and the outside diameter of a wagon wheel to make a precise fit.

I believe it is a Wheel Wrights Travelers measure wheel for measuring the inside of wagon wheels.

That there is a wagon wheel measurer, for measuring the diameter of wagon wheel biscuits. Getting the right diameter means you have just enough jam to marshmallow.

It actually the pizza cutter used to cut the largest pizza e ever in the history of ever in the second edition of the book of world records. The next largest pizza ever in the history history of ever that broke the first pizzas record required the largest pizza-cutter ever in the history of ever to cut it, so this one was retired.

A Ground Downer Wheel for locating the direction of the ground. BTW, it' s usually down, therefore the Ground Downer Wheel production was discontinued rather quickly. You can usually find one of these in the back of any given garage, hanging on a nail with the arrow still pointing towards the ground. Oh, Ground Downer...ceaselessly working even through neglect. It's almost beautiful.

It looks like a surveying wheel. It probably measures in yards but the ones at my school measures metres. You start with the zero at the arrow and walk, the ones at our school click every metre and you count the clicks to measure the distance you've walked.

It is a giant compass, but oh no, it is not one for the detection of magnetic north. It is simply too heavy and unwieldy. This is a compass for the detection of heavy metal. Best bought for and used by your close heavy metal enthusiast this will help them ensure that they will always know where the next concert is.
