I took a chance on this one in spite of the sellers pics, so hopefully I got it right.
Until it arrives, the sellers pics will have to do. It's badged to GHQ India and has what appears to me to be typical Indian markings, N over a 1in a circle I think means 1943 size 1, though I'm not sure what the other marks mean. The insignia is pretty mothed and though in some of the pictures the BD looks blue, I'm sure that is just bad lighting. It also has medal ribbons for the 39-45 star, the Burma star and the defence medal.
The only thing that threw me out is the pleated pockets matched with exposed buttons, so a hybrid P37/P40, so maybe using up old stocks of pockets?
I'll post some pics of my own when it arrives.
