Oxygen Mask?

[JK1945]

I purchased a type C Second Pattern flying helmet with MKVIII Googles and Oxy Mask some years ago while on leave in Aussie, however i have know idea what type of Oxy Mask this is and have found no photos of it on the net or in books . Im assuming it is late Forties early Fifties. The googles are named to "F/LT Bergh" and what looks like "48". Could someone please enlighten me as to what type of oxygen mask this is?

Hi,
I've looked through my only reference (Mick Prodger) and it is definitely not WW2. It looks like the next step up from the H-Type mask - early jet age as you say. Try posting it here:http://www.network54.com/Forum/180748/

"this is a post war A13-A pressure demand mask. American origin but converted for British use in the 50's."
