It is worth considering the rarity and the importance of the first pattern LRDG shoulder titles.
The change from LRP to LRDG took place in December 1940, and the SAS were not formed until the 1st July 1941, which means the first pattern LRDG shoulder title is truly the first official issue of British Special forces insignia of WW2.
The following picture was taken in 1941, it shows the first pattern LRDG shoulder title being worn and a New Zealand Onward cap badge.
