That's why I love it that my dad can fix anything. He has fixed so many machines for me. I bring him machines from my 4H girls and ones that people at church say take this to your dad for me. He loves tinkering with any small machine. That's one thing I don't like about the new computerized machines. It costs so much to have them repaired or just tuned and cleaned.
You got a great deal on her and I'm sure your mom will have lots of fun with her. Good eye! Just like anything else, you can find machines that people got and never used for whatever reason.
