The woman I bought these from said her father (b.1927) bought these on a family vacation in the Southwestern United States and never wore them.  The box says they are size 9.5 and were Made in Brazil.  I can not confirm that this is in fact the original box.   I am a size 9.5D and these fit me perfectly.   Light wear consistent with decades of proper storage.  Not even broken in. Super thick leather.
