You may call it tulwar on the basis of general construction and the general style of the handle, or you may call it tegha due to its wide and massive blade. That's the matter of personal preference and does not matter much : either name means a long-bladed weapon, a sword.
What is obvious, this is an Indian blade with a spurious European style mark.
19th century is most likely correct. Trying to pinpoint its origin by the style of the handle is an exercise in futility: handles were changed left and right and quite likely it was a second or third marriage for both of them.
