The USS Irex SS–482:
Right portion of the crew pictured in 1956

[ right group ]

Hopefully, with your help, I'll be able to identify these faces. Since the three at the left are in the previous shot, that leaves three rows of four plus Mr. Fakourey in front to the right (Ernie's brother). Starting from the rear:

Bobby Kreeger: Torpedoman Pappy Ayers: Cook Dutch Larch: Chief of the Boat

Art Callahan: Quartermaster Joe Quinn Rodney Snedeker: Quartermaster
