RAF 'Pathfinder'

[Mike Jackson]

This is completely out of my area of knowledge, but I find it most interesting. Stitched with other badges (cloth formation signs and RAAF Pilot's wings) to the inside pockets of an Indian -made BD blouse worn by a QAIMNS Lt (Nursing Sister) in India is a gilt (?) RAF badge with 54mm wingspan that seems to fit the Pathfinders' badge descriptions. It has screw thread posts and although difficult to read - since it's stitched to the blouse - is maker marker LUD....... LONDON.
An expert comment on this item would be very welcome.
Thanks, Mike
