Help cleaning a Wootz Talwar + comments

[AkaaliSingh]

Greetings all! i don't post a lot on here but love to read on here. anyways i picked up a very nice talwar with a shamshire like blade.

options? its a wall hanger that came from a pub for 60+ years. due to this the blade is darkened with smoke etc.

i've tired to clean up the blade with sand , after hours here is the result. the blade is wootz as the spine has the forging lines or "crack" that most wootz blades carry.

can anybody advise me on how to clean up this piece any further and how to also etch the wootz pattern out? will lemon juice just do the trick?

and also any comments on what circa and place this sword comes from?

i'm thinking 1800's... and south indian? the blade seems older to the hilt...

and any idea for the little pommel coming of the hilt?

thank you waiting on your replies!
