I'm afraid it doesn't matter. I don't think this sword belonged to him. There are handles that are very simply decorated, with poorly made inscriptions often with errors and missing characters. Such inscriptions always start with "Shri Baldev Ji Sahai" but what's next doesn't matter.
In the best case it is possible that such swords belonged to the rajah's servants or officers.
