As I've mentioned a couple of times, this cap was sold on eBay as a 'repro'...the listing quite clearly stating a 'museum quality knock-off'! All of the 'repro' insignia and authentic looking sweatband is 'machine stitched' which means done at the time of assembly...so this is your first encounter.
