East India Company ceased to exist as a colonizing force after the Sepoy Rebellion in 1859. So, this  tulwar is most likely first half of the 19th century. 
 And the geometry of handle is, IMHO, just a well known Udaipuri. Most likely Mughal. 
 
 However, things can be more complicated: handles and blades were interchangeable, and a chance of getting the original pair is not very high. 
 That's why Elgood wrote that Indian swords in the Victoria and Albert  Museum , mostly collected before ~1870, have not original handles, but those in the Wallace collection ( bought after ~1870) sport original ones.
