Wood Crock ?

I have not been able to identify this piece at all by looking under crocks.It has nice tongue and groove panel on exterior and it looks like a porcelain lined interior.I have not been able to identify it probably because I do not know the correct name for it. Any help would be greatly appreciated. Naturally almost everything is for sale for the right price so if I get the right offer it is for sale.It does have some writing on the bottom but I can not make it out. Thanks for any and all the help!
