So happy for you! It is a nice feeling when a machine goes a great job. I bought a brand new looking Kenmore at an estate sale for $35.00, including accessories and the manual. Try to Google your machine/model number online. I did that with mine and found mine was made in 1977 before plastics were used. It is also quiet and runs beautifully. I took it to have it cleaned and tuned up, and the sewing technician was VERY impressed.
Enjoy your machine to the hilt!
