Hi
There is not one source but many sources
It seems that there is no list of factory/French state with F-Axxx/W-xxx/c-n
All the existing info are mixed to obtain a "DIY" work : Accident report, individual logbooks, archives from training schools, F-Axxx register etc.....
I enclose a gendarmerie report which gives M-293 (read W, M upside down !), c/n on fin and French unit.
Attachment 19129
With these info : CAUDRON 275 LUCIOLE n°8025/F-ARST/8025 W-293 of EEP 36 at La Roche sur Yon
