Pictured is Luftwaffe test pilot Rudy Opitz, July 30, 1943. He is wearing a headband with a small 35 mm camera mounted to it to record instruments during test flights. Picture taken from recent aviation magazine article on early theory of high speed compressibility and Mach speed. Nice rig!

Excellent and very helpful, detailed shots, Bones, that certainly help clear up the differences between these two models. This is the sort of reference (using specific examples in a side-by-side comparison) that makes the forum such a great asset for all of us, I feel. Thanks. Of interest is the fact that eBay has both of these types up for auction at this time, if I am not mistaken. Also an RAF G helmet and a few others. Too bad there is not more interest in RAF gear, as it is not only inherently interesting, but in many cases critical for understanding of the original inspiration American researchers drew upon for US counterparts from pre-existing RAF developments.
Cheers, DocBoink

Greetings all, To get back to the discussion of the RAF type-B helmet and the RN type C helmet. I am attaching photos of both next to each other. You can notice the difference in construction and set up. It is also interesting to note that the Ox mask "clip" is held on with screws, on the RN type C. The RAF type B is on the left.
Enjoy, Bones

Bluelight & Doc Boink, The way the mask is attached is a strap around the helmet, the D mask has two snaps on each side that snap to the inside of the B-helmet. The carrier looks like the D-mask because a lot of Type D masks were converted. I will get out the old digi cam and post some photos of these items.

Hi DocBoink, I am trying to sort out the D versus microphone carrier using "Flying Headgear of the World" as a reference. It looks as if you are right about the D mask. The giveaway is the hose protruding from the sinister side of the microphone. It must be the oxygen hose. If you have the abovementioned book it is shown on page 21 (only the stud is visible, no hose is attached)
Cheers, Bluelight
