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

Hopefully, with your help, I'll be able to identify these faces. To the left is probably John “Dutch” VanDerHeiden (rather than Chief Hannon), and otherwise the three rows are, starting from the rear:

Wayne Puntel	Haas: After torpedo	Lemieux; Radioman
Bill Heagney		Wally Russian Krupenevich: Torpedoman
Hence Moore: Steward		Art Callahan
