Thank you for viewing. This is a non-sale MA-1 flight jacket related to the Nakdong River pipeline project in Gumi, South Korea. It's a collector's item featuring elaborate embroidery on the back. It's being sold as part of an estate sale. Condition: No noticeable stains. Some fraying in the back embroidery. Zipper pull tab is broken. Color: Green Size: No tag, no size indicated. Sleeve length approx. 63cm, body width approx. 60cm, length approx. 64cm. I am 170cm tall and it fits like a size M~L. Features: Back embroidery (NITROGEN, NAGDONG RIVER, PIPELINE GUMI KOREA) The zipper pull tab is broken and missing. Currently, it is opened and closed with a wire (see photo). The zipper itself can be opened and closed. This is a very rare and hard-to-find piece. I will sell it to someone who understands the condition and is a collector.
