Picked up what I assume to be one of the above.
6*24?
Knurled bending bar nut with elliptical plate under.
Catch is missing.
3 prism plate screws.
Grub screws on occular tubes & Objective lens housings.
The prism plates are unmarked!
It does not look like anything has been been defaced. Just smooth plates.
The only marking is part of a broad arrow mark on a bottom prism plate.
No serial no etc.
Any ideas?
