Johnston & Murphy CROWN Aristocraft ( U.S.A. ) question

[malocchio]

I wear 10C in modern Allen Edmond's top line dress shoes . I'm looking at a vintage pair of Johnston & Murphy CROWN Aristocraft shoes in 10C . These are USA made but I'm not sure what year . They have the comfortable Trampoline sole and are brand new

.. Any of you guys old enough to know how the AE sizing compares to the old American made CROWN sizing ??
