It's true that as a physicist I don't use APA style citations in my daily work. But what I suggested to you is not my reference structure. It's the
University of Illinois' reference structure, specifically for APA style citations, and specifically for the kind of book you are citing. What is the inconsistency between the APA manual and what the English faculty at Urbana-Champaign is saying? (Please don't feel any pressure to answer this. Your pre-submission stress level must be bad enough as it is, and I don't mean to add to it.)
If you absolutely must leave out the "reprinted from:" part -- which I doubt -- the direct answer to your question in the initial post is that you use the later date: That's the edition you're quoting from. That's what you want your readers to check your publication against. This is especially important here, where the editor changed the article before including it in the book. If you cited Author (old date) instead, your readers would end up checking your publication against a text you weren't working with.
