Olympia 1959 SM4 “S” Typewriter

1959 Olympia SM4 Serial # 1404754 Light blue in color. Paint is worn off in areas. I’m working order but would benefit from a thorough cleaning and service. Some keys will stick randomly. That may clear up with oiling. Needs new ribbon Case is included but the latch is broken and a portion of the latch was removed and remains in a ziplock bag. I spent about one minute trying to see if I could easily be repaired and it is doubtful. The rest of the case is structurally sound but has some material peeling off at corners. Feel free to ask questions.
