    LSM(R)-403 104k USS LSM(R)-403 crew photo, San Francisco, CA., circa January or February 1945. (Reverse side of the photo) "This is about three-quarters of our crew. The other quarter of us were on liberty when this was taken. Notice our dog. His name is "Rocky". he has more sea duty then half the guys in the Navy, and has been overboard about the same. The marking on the side of the picture is covering one of our rocket launchers. The large ship to the stern on the right is the sub tender "Bushnell", notice subs on the sides." The crewmember in the first row far right is Signalman John Sajtar (deceased). Identified by his daughter, Ann Sajtar. USS LSM / LSMR Association
