Here is an older, pre-owned red globe for a kerosene or oil lamp.   The globe stands about 4 inches tall as close I can get using a tape measure.  (Pictures provided.)  The top and bottom mouths are slightly different in size.  The top mouth has is about 3 1/8 inch diameter when measured on the outside of the lip.  The bottom is about 2 3/4 inches on the outside of the lip.  I do not have scientific measuring tools and use a tape measure.  Pictures provided.  No label or maker evident.     Please see pictures and ask any questions.
