Well there have been some developments on this, so I thought I'd add them here just in case anyone apart from me is interested
Firstly, in addition to those here who have helped, I need to thank: A. Alnakas, Rahil A., Sancar Ozer and Manouchehr M. Khorasani for their kind help in working on this.
The options now seem to be that it says either 'Shamil Mohammed' or 'Amal-e Mohammed'.
Also, it has been 'featured' on the website of Mr Khorasani.

This sword is a favourite of mine and I think that I now have as much information about it as I'm likely to get.
So essentially I am content now. There is nothing more frustrating than knowing you should be able to solve the clues about a favourite weapon and not being able to do so. I think its important to try and tell their story if you can.
These weapons are the footnotes on the pages of history, albeit inked in blood.
