Help needed with Tulwar.

[Pukka Bundook]

Just purchased another old Tulwar off e-bay and need a bit of advise.
It's been a very nice sword at one time, but I'm a bottom feeder when it comes to these things!
The seller thought it had been covered in silver paint or something, and I thought; "Good!....there might be something nice hiding beneathe all the crud!" (Some of the pictures showed promise)

Well, it arrived just in time for Christmas!.....and news not all that good.
It has been dipped in some kind of acid to eat off all the rust, and the silver in the photos is just bare metal.
It looks sand-blasted, but isn't, as the remaining silver does not have the same pitted texture.

So, My question;
What do I do with it now????
The blade is really nice folded steel, but with No finish remaining. (sharp as a lance , too!)

This looks like another opportunity to work on an old sword, without doing much damage.
Any ideas how to proceed?

Thank you in advance and hope your Christmas was Merry!

Richard.
