You’ll notice in my photos there’s no reflection or glare from the glass.
This is achieved by the gauge not having any glass.
This 6 lb 12.0 oz gauge is 8-3/8” across its face and 2-1/4” tall
Unknown where it was used, but Albuquerque had mines way back when.
While the needle moves with my finger, it doesn't return to zero, it returns to 10 (Might need an adjustment)Also note there is a dent to the bezel outer rim area, (Might be why no glass)
