Thanks very much for all the information.
I have 4 swords with this hilt type 2 with straight and 2 with curved blades I must get them all out and compare the nuances and complexity.
One is a foreign curved blade so is it a Firangi Tulwar

I have come across to the world of ethnic Indian arms from the world of British swords and Imperial German bayonets because of the complexity of finding out what you have and the fun of research that goes with such pursuits so I can't complain!
I am off to the shop on Saturday as seemingly more items have arrived in which might be of interest. Pity it is January when funds run low but I will just have to grin and bear it.
