Keep it original!
If the wood splits off, whether by accident or from old age I would just open the split if it's still attached and reglue it. Or if the split separates it into 2 pieces, just glue, clamp and reattach. Magazines are heavy and any forces will create large stresses on the joints or in this case the long grain in the feet. That's not the end of the world however, because long grain is the easiest to repair. A proper glue in long grain is just as strong as the wood itself. As long as it was not previously glued in the split, you should be all good! Do not add any reinforcements whether screws or side panels which would take away from the original look and character.
The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)
