Tulwar or Khanda

[Andy Stevens]

This old Indian piece has got me thinking, is it a Tulwar or a Khanda? The blade is 29 inches long and 1inch at the tip. The false edge is 7 inches long. The blade has two fullers and an interesting mark (second picture). Another mark can be found as the ricasso (bottom picture). The weapon is heavy and feels very functional, a real fighting tool. Where do these swords come from and who used them? Thanks
