Need info on Willar(d?) stove

I found pieces of an old cast iron stove, labeled “PAT’D 1881”, “LOUISVILLE, KY”, “No 25”, “WILLAR” and “MNF.rd BY” in the ruins of a cabin that figures into an historical article I’m writing. Photos of the pieces are attached. I would like to incorporate any info you might know about this stove into the article; particularly if you have a photo of a complete stove. I would give you credit for this info.

Thanks,

Dan Jones
