On display at Planes of Fame Air Museum. This sailplane was built during World War II to train cargo glider pilots. It had a single wheel instead of a skid, and the fuselage had a steel-tube structure, weighing 475 lb empty. The USAAC placed an order for 75, followed by 75 more. These were given the designation TG-4A, but the flight characteristics were quite different to those of a cargo glider. After the war, these "L-K" gliders with a 23:1 glide ratio were used to promote civilian gliding, and some were modified to achieve higher airspeeds.
