Ten 2 man tents are seen in the SAS Camp after 33:49 minutes. Then at 34:53 when you see a wide angle shot of the camp these tents have gone. The main problem is that the future occupants of the tents do not appear until episode 5 and will be seen around those tents near the end.
On 29th December 1941 the moon was a waxing gibbous, not full. And it didn't set in Libya until 0407 the next day, not around midnight.
If the Moon was full as shown, it would be at its highest near midnight, and wouldn't set until sometime around 6 a.m.
Shots of the airfield at Tamet airstrip, Lybia, show Hispano Buchons interspersed with Messerschmitt 109's. They are recognisable due to larger belly air scoops, higher engine exhausts due to Merlin engines and have 4 bladed propellers rather than three.
