Indian Tulwar with "Human Figure?" mark
 

Here is a standard, quite ordinary Indian tulwar with heavy and strong blade, the hilt used to be covered with silver but all silver is gone now. Original scabbard covered in old velvet/silk. The blade is stamped on both sides with what appears as a stylized "human figure" mark. Any ideas on this mark? Many thanks.

? - Devanagari 'four' ?

looks a bit like the number four, except isnt curved in at the top and theres a dot below. cant think what else it could be

Hi Alex,
The last of your pictures, the one where you show the mark, at which side is the hilt to the right or to the left?

Jens, the same mark was struck on each side of the blade: 14 cm from the base on the right side, and 17 cm on the left side. The same orientation - the "head" is oriented toward the tip of the blade, and "legs" toward the hilt, so on the picture the hilt is to the left.

OK Alex, then the number '4' is out of the question, as inscriptions/marks are seen from the hilt, and this would mean that the number '4' would stand on its head - which is very unlikely.
I really don't know what it is, but should I guess, and I mean guess, then I would say it is a makers mark, or possible an armoury mark - but why on both sides of the blade?
Jens

Thanks to everyone for comments, and thanks Jens for confirming "not 4" verdict (very clever, by the way:-). I tend to agree - this is just a mark, maker's, armoury, etc.
