I don't think the wood is Indian as it lacks the typical transverse wood screw through the forend in front of the magazine well area. Also, if it was new Indian production I'd expect to see the later riveted steel band reinforcing the back end rather than a brass pin. I believe the wood is "new old stock" walnut made at Enfield-note the superimposed ED logo on the underside.
I really didn't take the stamps as authentic. I am going to be disassembling this rifle very soon to see what it looks like under the wood.
