If you’re looking for a trio of cars to match the stainless steel fridge in your garage, look no further as Worldwide Auctioneers is offering a collection of three stainless steel Fords.

Set to go under the hammer at the Auburn Auction in September, the collection includes a 1936 Ford Deluxe Sedan, a 1960 Ford Thunderbird and a 1967 Lincoln Continental Convertible.

The story of the cars begins in 1935 when Ford teamed up with Allegheny Ludlum Steel to promote stainless steel which was still a relatively new material. In order to do this, the companies decided to make six stainless steel 1936 Ford Deluxe Sedans to “showcase the extreme durability and aesthetic appeal of the new metal.”

The models were given to Allegheny Ludlum executives and each logged over 200,000 miles (321,869 km) by the time they were retired in 1946. Only four examples are known to survive today and this particular model was retained by Allegheny Ludlum.

Following the success of the original collaboration, Ford and Allegheny Ludlum teamed up again in the 1960’s. This partnership spawned two stainless steel 1960 Thunderbirds and three 1967 Lincoln Continental Convertibles.

Both Thunderbirds have over 100,000 miles (160,934 km) on them and still use their original exhaust 60 years later. The Continentals, on the other hand, were pretty much stock other than the stainless steel bodies.

According to auctioneer John Kruse, the trio 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.”

There’s no auction estimate, but the trio are being offered without reserve and will undoubtedly attract a lot of attention.
