Question:
I have a five gal. red wing with a two&half inch wing. And a patented date of DEC.21 1915. Wondering if it has much value.

Answer: Your 5 gallon Red Wing crock is the later manufactured crock. It was manufactured between 1936 & 1947. Because it is later, smaller red wing and light markings, the value will be low. $40 to $50 in mint condition. Al Kohlman
