Hi folks,
I work at a technical college, recently we were having a tidy up and found an intriguing piece of equipment in a forgotten cupboard.
Anyone have any idea what this is used for? It seems to be some sort of rotary measurement device.
What really piqued our interest was the calibration date - 1946!
The blurry circle in the second picture is a magnifying glass that enlarges the linear scale.
Thanks,
Steve
