1 Points, Typewriter Hunter

1962 Sears Tower Challenger. I found it in the Sears Christmas catalog - page 308 of that year. Model number 871.1900. It works but needs a little TLC. I want to get it in good working order so that I may use it on a regular basis. My birth mother used her typewriter for everything and I want to do the same. Need a reputable place for service, repairs and purchase a new ribbon.
