Thank you very much for the replies and welcome!
I'm glad to hear they appear genuine to people with more experience than myself. Also very interesting and grateful to find out about the markings! I probably should get a book on Tulwar or Indian weapons. If the arrow is a Rajput clan symbol could it possibly be evidence that that one at least is from Rajasthan? There are also a lot of chips in one of them that definitely look like its been struck by another sword (to me at least) multiple times, not sure if anyone can see that on these pictures. They have definitely been sharpened before at some point. Could that mean it was used in some form of "well known" conflict?
Many thanks for all the help!
