One of the Regulars
Totally agree with you. Its hard to make both points at once regarding value. I do think there is a point where some things just transcend provenance. In this case, as you say, a 40s Aviator is a 40s Aviator. The rarity and vintage perhaps make the lack of a label of little consequence. And this jacket being a larger size (or at least its not tiny!) also adds value to it. I'll be curious to see what it brings.
The cossack is sadly too small. I never see those in larger sizes. I wonder about that hide?? I'm probably overthinking it but it LOOKS like it could be Calfskin...... I'm not able to close up on the pics for some reason. But the photo with the label looks like Calf to me. Totally speculating here....
Hopefully the aviator will go to a good home.
Can't help with the leather on the cossack, unfortunately; not enough first-hand experience with these old jackets.
