Vintage Keuffel & Esser K E  Site Marker

Surveyors level, in the original case
Case is metal, base is plastic
Latches have some rust but are solid
One scrape on top of device
The threaded eyepiece cover is missing (9th pic)
I don't know what effect that part has on the sight
I tested the telescope and it's powerful and focuses
It focuses with the black knobs on top
Has all four level adjustments on bottom that turn very smooth
It's held in case by a wing like nut that goes up from the bottom of case
I don't know much about these so see pics as it may be missing something I'm not aware of
But it seems to be all there, less eyepiece
