![It’s On eBay: Vintage Nettleton Shell Cordovan Longwings](https://staging.putthison.com/wp-content/uploads/2010/04/tumblr_l0b4qgHIRr1qa2j8co1_1280.jpg)
The shell cordovan is easy to recognize – see how the leather rolls, rather than creasing? Shell is the leather from the rump of a horse; it’s quite expensive but exceptionally durable, and almost never needs more than a brushing to shine. Nettleton were an American manufacturer who ceased production in the 80s, though the name was licensed for a bit thereafter. High quality shoes.
