There aren't any cracks on this insulator, but there is a very fine chip on one spot (see the white mark) and the bottom half of the glass is "brushed" from rubbing against something. I wasn't able to find a good date range for this, but Brookfield was prominent around 1870s to 1921 (when they closed) making glass insulators. I believe that this is the Beehive style of insulator.
