Response from Franceschetti:
"In this case "Cordovan" isn't horse cordovan, but it's the name that our supplier, a french tannery, uses to call this high quality calfskin. If it was original horse cordovan, surely the shoes would have been much more expensive."
Looks like the ebay "shells" sold out. Count me among those burned. Live and learn I guess. That being said, they're pretty dang nice.
