No, I have not tried to etch it yet, but I will try it, when I feel I have the time being on pension can be rather time consuming

Here is what most Kishangarh armoury marks look like. I really wonder why they made the marks so sloppy. It would have been easier/faster to remove the wax where the letters/numbers were to be and start etching, but they removed the wax around the letters/numbers, and in a rather careless way at that, unless the army just had come home with 25.000 new swords and daggers to be marked, before they entered the armoury. Even a stamp would have been a lot faster and easier although the number would fail so why etching?
