Antique Singer Sewing Machine with Original Wood "Parlor" Cabinet and Extra Parts

It belonged to a family in Monterey California, of whom I purchased it from. They told me it originally belonged to their great Grandmother who was born and raised in Albuquerque New Mexico. They're last great relative passed away leaving the sewing machine and other antique pieces with them.
They said that before their grandfather passed, who was the son of the Great Grandmother, who first had the sewing machine, he wanted to get it professionally refurbished to look the way it did when his mother was alive. He kept good care of it, which is probably why it still works so amazingly still today. But he never was able to get a professional to do a full refurbishing done.
