This ebay auction is for only the telescope off of an old surveyor's transit. It would be nice to know the story behind this instrument.
It was probably from one of the Ford Plants and used by Ford employees who were Millwrights when they were installing equipment. It's style and finish look pre- 1930's to me.
The GM plant that was once here where I live had several transits and levels in their tool room for millwrights to use.
