The work on Yorke Island was recogized by Heritage BC on Friday, 10 May 2019. Well done!

Just discovered another regimental history mystery. Let me walk you through the issue. 15th Field Artillery Regiment RCA was amalgamated with the 43rd Medium Anti-Aircraft Regiment, RCA on 15 October 1959 and perpetuated the history of that regiment. The 43rd Medium Anti-Aircraft Regiment RCA was converted from the 43rd Heavy Anti-Aircraft Regiment RCA on 18 August 1955 and the 43rd Heavy Anti-Aircraft Regiment RCA wes redesignated from the 11th (Reserve) Anti-Aircraft Regiment RCA on 1 April 1946.
It's a long trail but it shows the path that our regimental history follows as we consider who was a member of the regiment in the past. On 6 May 1944 the Daily Orders Part II for the 11th (Reserve) Anti-Aircraft Regiment RCA lists those Other Ranks that were granted Subsistence Allowance (a payment for those on full-time service living outside of a base facility to pay for ffod and lodging) for the period 1 May 44 to 31 May 44.
On that list is K.415023 RSM Cook, G.P. who was later taken on strength of the 15th Coast Regiment RCA as a Warrant Officer Class II. On ancestry.ca I have discovered a photo of a Percy George Cook wearing an Artillery uniform.
Have I connected all the dots correctly? Is this yet another lost RSM from the past?

Private Richard Roy Atkins, MM was a member of 4th Machine Gun Company when he was awarded the Military Medal on 23 April 1917. His citation reads:
​On the 14th April when on a gun crew in an isolated position, the enemy (during a bombardment) made a direct hit on the position, killing the N.C.O. in charge, and one other man, and fatally wounding a third. Although suffering from the effects of the explosion, he dressed the wounded man, and remained on duty during the bombardment, until finally attracting the attention of some infantry, sent a message for reinforcements to his Section Headquarters remaining alone at duty until these arrived. He has always shown exceptional bravery and devotion to duty.
Private Atkins went on to become a Cadet, training in the RAF and a T/Lieutenant with 11th (Reserve) Anti-Aircraft Regiment RCA in 1944. ​
