I have just bought this Autocollimator yesterday. It's a Hilger and Watts Microptic, no idea how old it is but I'm guessing 1970's at least.
I got it to compliment my repeat-o-meter. They have several uses in the workshop, primarily it'll be used for evaluating surface plates but they can also me used for aligning machinery and assessing (with the necessary adapters) machines for wear.
Sadly I didn't get a mirror with it, which is an absolute necessity, but I have managed to obtain several of various quality which are all loose. Now I need to make some mounts for them.
The large round one is by far the best quality but the larger rectangle one despite being scratched reflects the most light. The small one is - small and the one in the anodised housing comes from a laser scanner. It reflects well but drops off quickly over distance.
The proper mounted mirrors for these are usually expensive, and not very common. They seem to be one of those things that people collect and hoard.
If you want to know what an autocollimator is, and does, here's a youtube video thatexplains it:
