Marwar(???) hilt and a Gill's blade

[ariel]

Hi everybody!
Need your expertise and advice.

In his book on Indian weapons , Pant shows a hilt he specifically attributes to Marwar based on the " kissing swans) on the D-guard.

I have 2 similar ones. Regretfully, Pant, IMHO, is not a very reliable source of information.

So, my question #1:
Does anybody here has an independent confirmation of the Marwari origin of this pattern?

Then, question #2:

The upper sword has a standard Indian blade. But the lower one has a British 1796 pattern blade. I know that Brits transfered ( sold?) their blades to the Indian contingents.
This blade is labelled on the spine with the name of I. Gill. I know of Thomas, John and James Gills, but am unfamiliar with I. Gill. Perhaps, the letter of the initial is damaged. Does the stamp on the blade help?

I will be grateful for any help.
