Hello, just wanted to start by saying hello to all, I am new to the forum but can already see that there are some very nice people here! Anyways, onto the topic, I recently (about 2 weeks ago) purchased and received a B3 Jacket from Flightjacket.com (US Authentic) and let me just say this....The jacket is amazing. The quality and attention to detail is amazing, not to mention the customer service that comes along with ordering from US Authentic. They also guarantee their jackets forever, any repairs or anything needed to be done to the jacket, they will do it, no questions asked.
Now, I have never seen in person another B3 before, so I can't say whether or not one is better than the other; many manufacturers made those jackets throughout the war and they all did it their own ways, so in the same sentence I CAN say that that is what makes them such amazing jackets. It's their uniqueness and differences.
I paid about almost $700 for the B3 from them, (i had it custom fitted and made), but I would say it was worth every penny. I've scoured the internet in search of this jacket (to find the best looking one for the money), I originally wanted to buy the B3, but then upon seeing the price tag that came along with most of the jackets, I immediately turned my head. I did exactly what you did Blackjack, however, after searching and searching and just finding nothing but stripped down commerciallized versions of the B3 and Irvin jackets all over the web, I was kind of taken aback. I realized that there are no substitutes, if you are going to buy a B3 or Irvin, you buy an authentic one...no exceptions, and you will be so thrilled when you do. Trust me, this is coming from a guy who was in your same exact shoes. After seeing so many of the dumbed-down versions, it just made me want that authentic one all that much more. I know you were saying you don't have that amount of money to spend on it, however, like MikeyB17 was saying...if you look, I know Aero Leather has their used section and sometimes have the B3 on there, it's just an amount of luck I guess. But do yourself the favor, and don't settle for anything less, scrounge if you have to, and you will be extremely happy that you did in the end. I can certainly vouch for that!
