Appologies for doing this in English, but I think my English will be easier for you to understand than my French :-)
The T-33 at Chateaudun is quoted as being 51-6524 with c/n 580-5962. That doesn't match. The USAF 51-6524 was c/n 580-5856. The 580-5962 was in fact the 51-6630. This also makes it more likely the 16524 at St Dizier is the real 16524.
