This is a rare antique precision measuring device made by Troemner from the late 1800s to the early 1900s in very good condition.
The piece may be made of mahogany and has its original finish.
The item appears to be complete and working except for one knob used to raise and lower the front.
The front can still be raised and lowered without this knob.
Otherwise, the everything is present, including a separate box containing original fine measurement weights.
The bottom has leveling feet and the piece is signed as pictured.
