Dave, thank you for that link. Model name 'Nassau'. Sharkskin. 1972 collection. I don't know what, if any leather conditioner would be used on those to keep them alive, or has the leather already become brittle?
thanks guys, that is incredibly helpful. I would have never guessed AE did sharkskin! and no, the condition is actually really good, nothing brittle about them. They were one of several dozen pairs of AE's left behind by my grandfather, most new in box.
