I found this presentation box from the class of 1922 U.S.N.A to LT.Commander A.E. Chapman. I am trying to find out more about Lt.commander chapman. I have found very little so far, all I have is that on Oct,1 1941 his signal # was 2272 and he was on U.S.S PE-48-PE ( A ) If any one could find out more, I would really like to know more about his carrer and this piece of history. Would any body know what this would be worth ? I have never seen one like it.. Thank you
