Yep, that's the one !
In the movie, the '109 is only partly seen in close up, from a couple of angles, for brief periods and, to the average viewer, would look real.
A few years ago, when 'off-roading' in the Lake District, I drove through Grisedale forest, and visited the site of Grisedale Hall, the PoW camp where von Werra made his first escape attempt. Sadly, only the foundations and some other stone work remain today, the Hall itself having fallen into disrepair and being demolished.
Another pilot from I/JG 3, Heinz Schnabel, was shot down at exactly the same time as von Werra, crash-landing a few miles away, and was also at Grisedale Hall. He was later transferred to Shap Wells Hotel in what is now Cumbria, (taken over as a PoW camp), from where he escaped, along with Harry Wappler, a He-111 pilot. They managed to bluff there way onto RAF Kingsnorth, posing as Dutch pilots, and took a Magister, intending to fly back to France or Germany, but ran out of fuel, and force landed, intact, near Great Yarmouth in Norfolk.
Having enjoyed a hot bath and the services of the Officer's Mess at RAF Horsham-St-Faith, Norwich, their true identity was discovered, and they were eventually returned to Shap Wells !
