Paging militaria-isti

I have been trying, with no great urgency, to source a second leather
flying-helmet and goggles, for reasons which will shortly become apparent on
ukrm. I have a rather wonderful Biggles hat already, which is very
different from those showing up on Ebay. Whereas the C-type has ugly open
earholes for 'phones, mine has leather, brass-zipped covers to hold them in
place. It is an authentic garment, with the doeskin lining and velvet
bands at chin and forehead, and in fabulous condition. Given the
sophistication, I suspect that it's probably post-WW2. Can anyone identify?

Slightly shocked by the prices on Ebay, which are in the £100-180 range.
Mine cost the then daunting sum of 10 shillings in 1971.

Thanks, but I've 'done' the goggles, although I see that they sell repro
flying-hats at a very sharp price. I'm mainly intrigued by what vintage my
old hat is.

 

Type B?

No. It has the straps on poppers to retain goggles, and also poppers for
the oxygen/microphone-mask. Also looks substantially higher-quality leather
than that one. Thanks again!
