Good job. I agree with you that this is likely the Sara Sala Plagier that signed the book. However, the database also has a Sala Plager at the same address born on April 15, 1927. While it is possible that they are the same person and the date was misentered, we can't be entirely sure. Though it is very likely that you have the correct person, we must mark this as a possibility.
