This is the 519MP. Sold as a collab through Mr Porter. It has gunmetal hardware instead of the polished nickel. I had it altered to have shorter sleeves and to have an inch taken from the back to shorten it, the seamstress couldn't get the front as short because of the belt. Owned for about a year. Other than the alterations, it's in great shape. Looks new in person. I'll remove the pins before shipping. I removed the stars from the eapukets, but I still have them and will ship them with jacket. They're easy to install. measurements in photos. I am 5'10" and 200lbs modeling the fit of the jacket. Removed the pins from the lapels and posted photos to show the damage as well as a blemish inside the left sleeve where the tailor got a little sloppy with glue. It isn't really noticable unless you're looking in sleeve but being transparent. Chest 23" Length (back), 25" Length (front) 26" Shoulder Width 18" Sleeve length 23.5"
