Way back in 1935, a company in Pittsburgh needed a way to show off their fancy new material, called "stainless steel." So Allegheny Ludlum Steel signed a deal with Ford to produce six 1936 Deluxe Sedans with stainless steel bodies, each of them to be driven by executives. (All six lasted for over 200,000 miles, some requiring engine swaps.)
Decades later Allegheny and Ford teamed up again, producing two stainless steel 1960 Thunderbirds and three 1967 Lincoln Continental Convertibles.
"They are extraordinary artifacts from a dynamic era of innovation for the both the steel and automotive industries in America. After lifetime custodianship Allegheny Ludlum believe that they deserve to take their place in a significant collection or museum where they can be more widely appreciated in a collector car environment for generations to come, and we are honored to have been entrusted with their sale."
