Omori Meter Vacuum Gauge φ52 White Installed until December 26, Reiwa 7 (2025). Purchased new about 30 years ago and stored unused. Installed in spring and used for six months. It works. Please check the lighting in the photos. Since I replaced it this time, The stay holes are small, so Enlargement with a drill etc. is required during installation. Wiring needs to be extended.
