In your title you write 535 and in your text you write 353! Which is the good number?
Nevertheless, both were used by the 2eDB ["Free French" 2nd Armored Division] but for transportation of fuel, ammunition or pieces and parts for the vehicles of the 2eDB. As you know, the 2eDB was made of different units (infantry, artillery, tanks, etc...) and each unit was made of sub-units among which some had GMC trucks used to perform tasks as mentioned above. Yes, I have several photos of GMC trucks of the 2eDB and Alain EYMARD, who wrote a book about the organisation of the 2eDB, has some also, I will see with him if he agrees to send you copies.
