The lens mount (which is cast!) has threads into which the two units screw into....the lens spacing as shown in the diagram is correct as far as right and left units are concerned. Spacing of the two main units to each other is correct within 1/4 inch. I am not sure how the whole assembly was mounted, and whether it was encased, and how. The retaining rings at the ends of the lens are well made and there is nothing missing there.
Given that the serial number was CAST with the lens mount, there must be quite a few of them. The recurrent serial is 1095-18xx, with the individual pieces then labelled with scratched in numbers.
