These units were used to inspect the surfaces of the multi platter
diskpacks, like a RP0x or RM0x packs.

I used to have one but was different to the one listed on ebay.

The one I had can be seen at this link :

Here you can see the armature with the strip mirrors, which would be
moved between the platters. The diskpack would rotate slowly and you
would be able to inspect each surface using the tilted mirrors.

Ik email, dus ik besta 😆
