Glengarry-Seperate Crown and HPC with Backing Plate

The use of a HPC with separate crown on the Glengarry can clearly be seen in this picture.  Although a backing plate was issued to make the HPC and crown fit together as one and make the badge ‘straight’, the jaunty angle of some of the crowns on the caps would suggest that not all of the soldiers in this picture were using a backing plate.
