Does the AE Cambridge only come in shell cordovan? I found a pair today and I was looking them up to see if I actually should have bought them and I can't find a regular leather version. The number on the inside wall matches the shell model number for cordovan #8 as given on this AAAC thread.
Excellent find! As far as I know they only came in Shell or Suede, unless you special order them in calfskin or some exotic material.
As said before, be careful with their list, there are a few calfskin shoes on it. I have a more complete list somewhere. I will see if I can dig it up.
