Four days ago I posted a thread in General Cast Iron regarding a bunch of cruddy rusty iron that I picked up in West Texas. Here are the results of three of those old skillets that were headed for the scrap yard had I not rescued them. There are two WW pieces and one Favorite Piqua Ware pieces. The #6 is prior to 1960, the #5 is a stylized logo w/ four digits from 1935-1959 and the #3 between 1916-1934. None real valuable but certainly gave me a good feeling to salvage them.
