I feel that a churn should be added that seems to be a little hard to find. The jar is high shouldered; the top is the unmarked top. The jar is marked as follows: No. 40 DAZEY CHURN, a round circle is molded into the center of the glass, which we believe was a place to apply the label, DAZEY CHURN & MFG CO, ST. LOUIS MO USA, MADE IN AMERICA. the only size known to us is the No 40.
