These were a great mechanics diagnostic tool back when I was a apprentice in '65.
Very simple and accurate and cheaper than any diagnostic tool nowadays.
I just cleaned it up. It still works fine. Just hook it into a vacuum line on the inlet manifold.
It also doubles as an old mechanical fuel pump pressure checker.
