Thank you Francis for the link. I did not remember I had given pictures for this study but in fact some of the images with my name are not from me... It is a very nice and complete study though. It seems to be confirmed that the plate numbering was specific to JP8... this is puzzling but I double checked my JP5 helmet... no number.
