public domain reprints
I also emailed about this situation with someone from Project Gutenberg, and she agreed with the conclusions reached here by the various responders - a facsimile would have no copyrights except for newer material.
For reprints with new typesetting, again she agreed that the original contents have no copyrights, but she cautioned about potential problems with subtle changes such as correcting original issue typos and changes in layout, etc. She agreed that ocr and elimination of page numbers will remove most of these potential copyright problems except perhaps with any typo corrections.
Thanks again for all the help with my question!
