Dav HB og velkommen til Vikingsword.
I canít help you with the kindjalís as I collect Indian weapons, but the tulwar seems to have an old blade, well used and sharpened. Have you tried a magnet on the hilt? The hilt is likely to be newer than the blade, or maybe decorated/plated at a later date.
The search button can help you a lot, so don't forget to use it
