Ibrahiim and Gav, thank you guys! Great catches on these comparisons, and both extremely relevant. I think these reflect the potential for associations with the regions most closely connected to the ports and Red Sea trade out of those now Pakistan. The elements of North Indian tulwars, blade and the rather unusual instance of globular pommel, as well as distinct Afghan features amalgamated together present a fasinating anomaly....at least until we find others like it
The globular pommel enclosing seeds or small stones as rattles is an apparant feature of certain Yemeni mounted swords known in Sudan and Darfur in particular late 19th c. used by mounted warriors in threatening foe, as described regarding some broadswords of kaskara type. Possibly this affectation diffused from those regions to trade entrepots connecting through Sind to Afghan routes.
