8 gallon Red Wing with lid

Question: Hello: We have an 8 gallon Red Wing crock with a lid.  It has a patent date of what appears to be Dec 21, 1915; marked Red Wing Union Stoneware Co., Red Wing, MN; and also has a red wing mark.  It is in near perfect condition.  Would be interested knowing the estimated value.  
We also have a two tone (brown/gray) crock with the only discernable marking of a 5.  This is in good condition – no chips. Would be interested to know if it is a Red Wing crock and the estimated value. 
Thank you.


lets break this all down.  The 8 gallon Red Wing lid has a value between $175 & $200.  The 8 gallon Red Wing crock $150.  The two tone crock is not Red Wing so no idea of value. Al
