Heavy/large talwar / thega sword

[Jim McDougall]

Here are some stamps of similar nature.
The first is thought to be from perhaps Gujerat and the Kattee people who use the katar as a key symbol of state. The trisula is of course an important Hindu symbol.

Next is a tulwar with the upper ricasso quadrant stamp, I believe Urdu cartouche and the trisula again in key blade location.

Next a tulwar with possbly Urdu cartouche and close up in next image.

Next a khanda with katar and trisula .
