3 Pulwars

[AHorsa]

Hi There,

I just acquired these three Pulwars. But it is actually not my field of collection, so I would be very happy if one can help me with them.
The overall-lengths are 93cm, 87cm and 73cm for the small one.
The middle on has an inscription on the blade, which is not readable and also I do not get it on an image clearly.

Is it possible to date them?
And are they all from Afghanistan or also from India?

Looking forward to your feedback.

Thanks and best regards
Andreas
