Hello - I have a photo of my father-in-law which shows him in his WW2 army uniform. His left shoulder/arm is facing the camera and the insignia is of an upright sword imposed on a backgroud of an oil-lamp (which is lit)? If this is familiar to anyone please feel free to point me in a direction. I have browsed through a few books and I have not seen this particular insignia......so far. Thank you.
