As shown on p.174 in Weatherman, "Colored Glass of the Depression Era 2", this bowl measures 7 in.
Although this bowl was shown in an Imperial catalog as Old English, it does not have the #166 line number associated with the Old English pattern. Items numbered #134x are also known by the pattern name Olive. This #134 line includes several more pieces than are shown in the Imperial catalog page referenced above. As there is some confusion as to which name is correct for the #134 Line items, both are included here.
