After the conversation about setting up cocktail hour, Seekings salutes with his left hand. Not done on the Britsh Army.
Most of the "Messerschmitts" at the German airfields are actually Hispano Aviación HA-1112 "Buchon" aircraft. This was a Spanish plane based on the Messerschmitt BF-109G model. It is the same airframe but the Buchon has Hispano-Suiza or Rolls-Royce Merlin engines. They can be recognized by their four bladed propellors.
In the shot across the airfield of Tamet (43:18) the view is not of Messerschmitt's, but of Hispano 1109 "Buchons" identifiable by the larger belly air intake scoop and higher engine exhausts as they are fitted with Merlin engines.

These weren't in service with the Luftwaffe in WW2 and didn't fly until 1954.
The word chaulk is used to indicate which group of soldiers is to board the planes. This actually wasn't in use until the D-day invasion.
Just after the conversation about where to put the piano, the shadow of a boom mic can be seen on Paddy's left shoulder.
