Righty O! First, 'Red 13' of 2/JG26. It is almost certain that this would have been up-graded to E3 standard, and probably served during the BoB, although a lack of Werke Nr can't confirm this. The Geschwader occupied 3 bases, at Audembert, Marquise and Caffiers, in the Pas De Calais, and I believe I Gruppe were at Audembert.
Now, 'Yellow 13', of JG54. This Geschwader again occupied three bases in the Pas De Calais area, at Guines, Campagne-les-Guines, and Hermalinghen, all of which were between Wissant and Boulogne. It was I Gruppe that occupied the field at Campagne. Note that the aircraft in your profile does not bear the III Gruppe bar which, although unusual, is correct for a 9 Staffel machine, and this Staffel, AFAIK, was based at Guines.
Several, but not all, of this unit's aircraft had the distintictive 'tiger stripe' mottle, whilst the other Gruppes had plain RLM65 sides, or a very pale, small mottle. I'm fairly certain that this aircraft did force land during the Battle, but I still can't find the bl**dy book!
Hope this helps old boy!
