Richard I know you have all this, but for Jerry's benefit:
Correct about the BD Jerry. Its from a 1948 Shooting team pic of 1RWF.
In Regimental Records it is also noted he was later Brig JRH Orr CBE..1908-1968
Service No 380336.
His CBE was added to his OBE for his Kenya service 53-55 with 70(EA) Bde.
His MID as a Brig!! in 1954 with 70 Bde.
His OBE was from his service(I assume as CO) with 23 Kings African Rifles in 1952 as a Lt Col. (possibly 2nd/3rd Bn)*.
*Wiki- 2nd/3rd Battalion, a reserve unit, was raised during the military phase of the emergency in Kenya and was under consideration for disbandment by 1957.[3]
