About the measurements of the lampshade quinqué:
In reference to the mouth of the lampshade, as well as its diameter, we must take into account Note that there may be a small variation of millimeters in the size of the mouth in the manufacturing process. We take into account the hole in it, but the outer diameter of the mouth is greater, since the glass raises its diameter a few millimeters.
To install the quinqué glass lampshade it is necessary that there is a sufficient base diameter to be able to fit it. If the size of the hole where you have to place it measures exactly the same as the mouth of the glass tulip, you will not be able to fit it or it may even break if pressed.
