20+ Year Old Horween Shell Cordovan
I recently stumbled upon some NOS (new old stock) Horween Shell Cordovan from a supplier. The first thing that was immediately apparent to me was that this shell was old. Not based on the quality or dryness (it was still quite supple!) rather the Horween Shell Cordovan stamp on the interior. It certainly isn't the same stamp Horween currently uses so I inquired with some folks at Horween.
It turns out this stamp hasn't been used for at least 20 years. It is a pretty cool find!
