Frederick Leck served as a Machinist's Mate on submarine chaser SC 129.
This set shows his chaser and several images of crewman Leck including a shot taken in the engine room.
SC 129 showed a star on the mast to signify a submarine kill (although official credit was not awarded for a kill).
Thanks to his nephew, Mike Leck, for submitting the images to The Subchaser Archives. See also, from the same collection, a photo of SC 129 in which a star is shown on the mast, representing a submarine kill.
