Definitely not Horween. The word "Industria" leads me to believe it's come from Italy. See this relevant post from a totally different forum:

Italian cordovan?

Say what you will about shoe snobs, but those guys know genuine shell Cordovan.

The reason these Horween shell strops are so expensive is because the material sourced from Horween is very expensive. But you get a time tested, undisputed best in class product with Horween shell. If the maker of the strop sourced the material from abroad, at best they're profiting significantly at your expense as you paid for Horween, and at worst, the material is no better than what's used to manufacture a belt in China.

You paid I'm guessing a heck of a lot of money for this strop. The maker advertised Horween and they are the provider of choice for top-tier strop makers. If I'd received a strop expecting it to be clearly Horween shell Cordovan and I received anything but, that sucker would be on it's way back to the peddler on the first thing smokin'. With a clean conscience.

You sent the seller money for a Horween shell Cordovan strop because that's what you wanted. Get your money back and get a Horween shell Cordovan strop.

This is what the stamp on the back should resemble:
