I had a look in some of my books, and found the attached picture in Contribution a L’etude des Armes Orientales. Vol. I-II, Paris 1931. It is in vol. II plate 15.
Although my French is close to non-existent, it was easy to see that the three katars to the right are said to be Deccani katars. I am not surprised as I had a feeling they were from Deccan. The katars, like your and mine, with only one cross bar, are likely to come from the same area, although I don’t know from where, and Deccan is a very big place to go looking, so you will have to be patient until we find some more hints
