I developed the patterns and the primo has never existed with any bemberg on the inside. The jacket in the photo is a tipo. You can also tell because the shoulder has more structure than the primo, which is completely soft with grinze. The only thing I can think of is that the jacket pictured is not what you will receive if you order.
As for model breakdowns, Ive done this before. If you search my posts you can find it.
Wow, very interesting! Not to question your knowledge on your own product, but this is the picture he sent, a Primo tag with Bemberg lining? Just trying to figure out his items before I take a plunge.
