I'm with you on this. In India they are making new dhals, kards, katars, etc. like this. I have rarely seen koftgari work that incorporates both silver and gold together. Certainly this example is a little too shiney - no patina on the silver nor wear on any surface what so ever.
I was looking at the yataghan. It may be older, but with a replaced forte on it. Don't know of many repo yataghans
yet .
However, the stamp on the blade does bother me.
