HandyWhip Jadeite Beater Jar

Featured for your enjoyment is a rather confusing beater jar. Made of Jadeite by the Chicago Electric MFG Co. Now it has lines on the side but no measurement marks, I have seen only one other and that has the measurement marks. I do believe this was also a double boiler of sorts as it says “Another HandyHot Product” also on the bottom. The larger lip would accommodate some sort of second pot. It is in excellent condition. Stands 5 1/4” tall by 4 1/4” to the outer rim and 3 3/4” across the inner rim.
