I just recently found my father’s old B-3 Bomber, claiming it was official US Air Force issue from, I’m presuming, 1978. Incredibly heavy and excellent build quality-super pumped to have it but also a bit worried it’s worth a ton and don’t want to wear it out every day if so. Any chance anyone recoginizes this tag and can say whether it’s just a nice jacket or is a proper vintage find that I’d be nervous wearing regularly?
