I inherited (from a building contractor buddy) a small tool/device. I
can't post a photo here, but the visually imaginative readers can
picture what I mean from the following description.

It is cylindrically shaped, about 1.5" diameter, 6" long, in a metal
case. Lens at each end. Acts as a low-power telescope. The top of
the device has a bubble level, with optics such that when standing on
one side of a room, and looking across it, one can not only see the
other side of the room but also the bubble level and a horizontal
marker. One can raise and lower the angle of the device so as to get
the bubble in the center of the markings, and that allows the user to
see, on the far wall, what is exactly at eye level.

I don't know what building or other application would call for such
information, but that appears to me to be what the device is designed
for.

My question is: What is this called in the trade? In what trade
would that be? Surveying? Plumbing?

Corrections to my understanding, and other comments welcome.



Maybe it's just an early surveyors scope without the cradle.
