Hello everyone, first time posting on here. Allow me to preface this message by saying that I don’t know much about clothing or men’s fashion as I am barely getting into the subject. With that said, I just wanted to ask for anyone’s input on this vintage n3b parka to learn some things about it; to name a few: The quality of its condition for its age, the actual year of its manufacture (I presume 1963?), proper way to care for it/clean it, how it compares to other n3b parkas, info on the manufacturer and their quality level of manufacture and so on. Any tidbits of info or anything you notice/think I should know would be nice. Thank you all in advance and have a great day.
