I would like to ask for some help identifying a cast iron kettle. Yesterday I purchased what I am guessing to be about a 20 or 25 gallon kettle. On the bottom it says Wagner Mfg. Co. Below that it says Sydney O both of these are in arched or in a circle with a number 6 in the middle. I have never seen one with a name on the bottom. At least not this big. Just wondered if anyone could help me with any info on this kettle? Anything about this would help and be much appreciated. Thanks
