Hello....Apologies to yourself...but I do not like forums discussing my items as to the rights and wrongs as I note they never discuss a "nice" piece.....I am retired and have been collecting Aviation related material since I was at School.I have had many hundreds of Flying Jackets through my hands and put a book together with Jim Weld on flying gear in the early 1980's..As with luftwaffe jackets there are many variations both private purchase and otherwise.As my description says this appears to be a cross between a B3 and an Irvin.This is exactly how I purchased the Jacket together with the RAAF badge.A group of WW2 Australian Veterans were here a couple of years ago for a reunion at Binbrook ..7 miles from myself and this Jacket was worn in some of the photos and purchased from one of them by myself.I have no reason to doubt it at all and if others want to then its up to them.That is all I can tell you other than if it had been a single seam IRVIN it would have been £475.00,and not £175,You cant buy a copy for that and this is certainly not a copy.I have had Canadian and Australian Jackets with one,two and no pockets..There were many others than the Govt issue as you must know.If I buy a Jacket from a VETERAN I take it as being original.The Quality of this is also excellent.. I am sure you can see my point with peoples views and opinions on a Vet item.This is the first time anybody has "questioned" the jacket also,indeed I have had Australians get back with interest!Please post this on the forumn if you wish....With Regards.
