What is this mysterious Zeiss part? Argon?

The label on the item bag, which is VERY faded, says:
Carl Zeiss Meditec AG 07745 Jena Germany
Pankrat Argon/MMP wit Ojbektiv OEM
00000-1388-549

It is possible that Argon could be something else…Aidon, but doubtful.
The label on the outer box says CZJ QS Rev A 542-1654-001

Below are pics. Note - no markings on the parts other than the zoom factor. Zoom is 50x - 1000x. The top of the piece is a bolt of some sort. There are screws and a lens on the bottom, I can only post one pic for now

Ahh - here is the bottom
