Tulwar inscription question

[Jim McDougall]

I agree with Rsword. The multiple arrangement of symbols in the fullers is often seen on early sword blades from Europe, and it seems that similar arrangements appear on Italian swords. The blades from Portuguese and often Italian swords were often used by native armourers in their firangis (Hindu basket hilts) and as Rsword notes, these numerically arranged symbols were likely intended to assert the quality of the native forged blades in imitation of the markings seen on the foreign blades.
It seems that the circled dot is a solar symbol that is seen on weapons in varied regions, but it seems to me that they often appear on weapon motif in Afghanistan and northern regions of the subcontinent.
The other markings in the arrangement seem like they could be sanskrit devanagari characters or associated symbols, but as yet cannot find anything similar.
Best regards,
Jim
