Unlike other regions India was slow into the business of faking age on weapons. Like all weapons it is far better to have the thing in your hands in assessing real or not. I have to say, however, that looking at the wear, rust and patina in these pictures that this looks like mid 19th century or earlier... It is naturally worn... I see no sharp edges and the overall smooth, even wear seems to me quite original. I can imagine that when it was newer the pearl or steel ball inserts would travel up and down the slots but that fair wear and tear has rendered the grooves unusable ... The Chinese were making this style in the 17thn C and it is suggested that it was something they copied from India and Persia. Certainly there are plenty of examples from those regions. Great discussion ...Thanks.
