No reason that I can think of not to do as Steve Gardham suggests. a "reprint" if you will be adding new text, it is a new project. Also, you should go to a printer who does this sort of thing, and avoid "do-it-yourselfing"--you'll save money, time, and end up with a better quality result.

Also, even though the original publishers are no longer in business, there is a fair to good chance that the original films, plates, and boards are in storage somewhere--if it is worth reprinting this piece, it is worth looking for them.
