Thought I'd post a pic of this. This is the first original example I have ever seen. I just purchased it. I have seen many M-422a's but never an AN type. Buzz makes a repro I know, that's the only place I have ever seen one before. I am replacing the knits, zip and mouton and turing it into a wearer. Looks like it had a large piece of artwork on the chest, shame it's long since been removed. Any clues as to what it may have been?
