Also on old uniforms, the 'owner' might have removed the 'wings', which were of significance, having been 'awarded', and then disposed of the uniform. I disposed of my original 'Dennison' smock some years ago (wish I hadn't!) but retained the para wings, as these were the ones presented to me and worth retaining, if only as a reminder of the achievement. At the time, the smock was just an old garment, and it was given to a friend who collects militaria.
