During at least 2 scenes on the Commonwealth tour, Prince Phillip is missing an EIIR cypher off one of his shoulder boards on his Admiral of the Fleet tropical uniform.
During the Queen's speech in Bermuda there is a Guard of Honour lining the rear of the podium. The Guard of Honour are equipped with Lee Enfield rifles which they are all holding back to front in a mimicry of a 'Present Arms'. The weapon would normally be moved from the 'Slope Arms' on the left shoulder to the 'Present' as a form of salute to the Sovereign. Holding the rifles in the position shown would be uncomfortable to balance and difficult therefore to move in the proscribed manner defined in the Drill Manual.
The Guard would also not hold that position during the speech. They would return to the 'Slope Arms' and hold at 'Attention'.
The Duke of Edinburgh compares the upcoming Commonwealth tour in 1953 "like giving a lick of paint to a rusty old banger", but the earliest use of the term "old banger" came about in 1962.
