Up for auction is an old cobbler's tool cast iron stand with 4 forms. 2 are very unusual, and I can't find much  information about them. These could be the Holy Grail of cobbler forms?  The stand base is marked  Patent March 9 1880. The 2 unusual forms have the exact same Patent date. They are marked June 18, 1872, Mar 9 1880. I found this all together. I've done a lot of research but can't figure out who made this pitcular set. I don't know if I'm missing any other forms. Please feel free to provide me with any more information if you have any.

Please ask me any questions before bidding.
