Angels and Women was not published by the WT. It was endorsed by them in the Golden Age, and reportedly the reprint/ revision of Seola was done by some of the Russell era Bible Students, but the fact remains that it was not published under the Watchtower label.
It might as well have been written under the WT label. The Angels and Women revision has 36 Appendix notes mentioned throughout the novel. All these notes reference publications of the Bible Students to support the passage in the book. The Appendix section quotes the following Bible Student works.
The harp of God
Studies in the scriptures volume I, II, IV, V, VI, VII
Photo-drama of creation
A desirable government
Thankfully the novel does not have a question for each paragraph.
