Thanks for all the info. It doesn't seem to be worth much, it is kind of cool though. I am amazed I still learn something new everyday. Have a good one.
My brother passed away a month ago and I was cleaning up his belongings I found this item. It looks like it had a bubble level on top, and the glass has some faint lines in black on it. I can't see through what looks like an eye piece at the end. I hope some one on here can shed some light on...
