Some time ago, one of the Griffins sent me this image of a newspaper clipping from the 1936 article about the results of the Civil Service Examinations for NYPD Sergeant. There were only 37 spots available, for the 1,345 men who passed out of 5,342 who took the test. Papa, Joseph E. Mulcahy, had the 3rd highest score, behind only Joseph M. E. Mallon and John E. Godfrey. I've had this saved for some time, but am only just remembering to post old documents now that I've figured out how to use Scribd.
