Others can know much better than me, I am not an Indian arms specialist at all, but as far as I have seen on ebay, and in real, general rules for today's factory produced Indian arms are:

Almost all of them have dull edges (not dulled down later, they have been just produced dull, cause otherwise it would cost higher, and would carry rsome risk of damaging the blade). They have thick sheets of blades with already dull edges.
The pattern is not hand forged but factory machine produced. All newly made ones have this kind of pattern. Antique patterns are quite different . Factory damascus flowlines can continue whole bladeway like in your pictures but hand forged ones cant do that. ( I hope more experienced friends here can confirm me or correct if I am wrong).
Most of the all-metal kind new arms have exactly this kind of silver koftgari. They are very skillful in covering everything they wish full with koftgari for really cheap costs, no problem for them.
Again, I am not an expert on the field and I cant bet on it, and hope to see comments of real Indian arms experts in the forum as I wonder if my informations are correct or not, and I hope they confirm the authenticity of your items.
