Air Corps Bomber Jacket inquiry

Hi all, I was wondering if anyone knows anything about a bomber jacket that looks like an ANJ-4 but has a triangular plain leather patch on the left side (chest). Any help would be much appreciated, Thanks

 

"In addition the two front pockets a triangular goatskin piece was installed in the front left side to attach the oxygen mask when not in use." (but still an ANJ-4)

they might not be the best source of info, but it sounds about right

Hope it helps and welcome to the forum

 

thanks nigel i appreciate your response and thorough information

 

You're welcome - give it a few more days and one of the crew uniform experts might well jump on with some more detailed info - personally I can't quite figure out why a triangular piece, instead of just a strap or loop....
