Afghani pulwar: old and ( perhaps) revealing

[ariel]

Jose,
Usually, such pommels are described as " onion-like" in the literature.
But even if it is solidly spherical, it does not change a bit: as I reported earlier, Google Images finds them in ~10% of cases. Most importantly, the one with white arrow is unquestionably just like mine. One is enough to prove the point:-)
Again, thanks to Mahratt to provide this information.
