I believe it's 165B. Length: 51.5cm Width: 51cm Shoulder width: 41cm Sleeve length: 21cm I received this as a new item, but I haven't had a chance to wear it. It's been stored in a closet for 3 years, so it's listed as "like new." Fully open in the front. The navy parts of the collar and sleeves are detachable. There are snaps on the inside of the collar (for attaching a ribbon, etc.?). The scarf holder is not removable. The white part is made of a fabric similar to a dress shirt. Three lines. No chest padding. Brand is unknown. Made in Japan. There is one stain on the facing from when I purchased it (inside, so it's not visible).
