Thank you for viewing. This is a genuine US military M-51 parka. The size is large. Measurements taken flat: Total length: 102-103cm (measured at the back) Width: 70-72cm Sleeve length: 63-64cm Shoulder width: 57-58cm Please note that these are amateur measurements, so there may be some errors. Also, there may be variations depending on where the measurements are taken. Please consider these as a reference only. As this item is approximately 70 years old, there are many repairs. I have included photos, but there may be some that I have missed. Please zoom in and carefully examine the condition. In my opinion, these repairs are part of the design and are characteristic of vintage military items. The buttons on the sleeves have been sewn on. The zipper works, but it's not as smooth as a new one. There are also scuffs, fading, and stains. The major damage includes a repair on the chest and scuffing on the hem. As this is a military item, there are minor scuffs and stains that I haven't shown in detail in the photos. Please assume these are present when considering the purchase. Since I purchased it, one of the hem buttons doesn't fasten, but I haven't used it. I haven't done any repairs myself since I purchased it... I know where the repairs are, but I don't know if the buttons or zipper have been replaced since I bought it, so please understand. I want to avoid any problems after purchase, so please understand everything and consider your purchase carefully. Please feel free to ask any questions about the condition of the item. Thank you.
