I found my old Knight's Castle (#6073) from 1984 at my mother's place. My 4-year-old and I were both so happy to find this treasure : r/lego

Another retro-build. Set #6073, Knight's castle. The front turret is modified b/c I didn't have the working winch for the drawbridge. My 5 y.o. did the knights. : r/lego
