Put WW2 zips and buckle on it, change the neck label, put an elastic strap on the collar... no more authenticity issues...Whatever the lack of historical accuracy this jacket has, or has not It is 100 times a better looking jacket than Aviation Leathercraft produce

Here's a thread dedicated to the subject, although it doesn't seem to get much traffic these days
