I adjusted the colors a bit so the label was more ledgable. It's not a very old bottle. I would say 1950s, guessing. My grandfather was a farrier. (sp)
I'll let anyone know if any bottles are avaiable for sale. I'll be at the farm this weekend and I'll take some better pictures and do some carefull cleaning to get better information. Thanks everyone for the information you supply, it's great to have a resource like this.
