Hi Maisie,
I definitely would like to see the photos.
I have a MK 1 in my collection which is posted earlier in this thread and it is Maroon, Silver and Scarlet. MK 11's that I have personally seen/handled also only have been in this colour configuration. All of these helmets reside here in Canada, strange that ones located in France would be Blue. The location of a farm in Beny-Sur-Mer is certainly a place I would expect a Chaudiere artifact to surface but the colour Blue is something I would not expect and am puzzled by.
The link to Clive's website with the picture of a MK 11 was actually a photograph I took back in 2008 while I visited the Chaudiere Museum in Levis, QC. In that picture, the decal is a pristine example that I believe was added to the helmet at a later date. Still, it represents what is supposed to be the colours of the decal.
I have attached a couple photo's of MK111's with decals that are clearly in the Maroon configuration. The better MK 111 was from this website which is located in the Netherlands.

At the moment I cannot locate my source for the other picture.
Best,
