Typically it's not good news to find another personalised inscription, is the name and dedication the same as this one? Technically these type of inscriptions were not produced by the manufacturer, this is not a "template" type etch. A thin layer of wax was applied and the inscription would be scratched into the wax with a stylus, so it is normal to see uneven text and hand-written type. Sometimes the lettering would be applied by a craftsman, other times it could have been done by the wearer himself, especially on a signature. Once the wax had been completed, the manufacturer would etch as normal in an acid bath.

If there are more than one of these with the same/similar inscription, I'd be concerned.
