    USS LSM(R)-524 Model
    LSMR-524 611k The solid mahogany model of USS LSM(R)-524 was built by Motion Models of Florida. It is 30" in length and 13" high at the top of the conning tower mast. The model is authentically detailed with the proper armament and pre-invasion camouflage color scheme for that era. The model, commissioned by Mark McDonald, was made in loving memory of his father, John A McDonald S1/c, and his ship mates who served in USS LSM(R)-524. At this time in history the crew was preparing for Operation Olympic. The first stage of Operation Downfall, the invasion of the southern most main Japanese Island of Kyushu. Photos by Mark McDonald
