50s CONMAR zip nylon duffel bag US. NAVY junk

This is a military-style nylon duffel bag from the 1950s-60s, featuring a CONMAR zipper. I purchased it at a vintage clothing store in Tokyo. The design is very similar to a 50s US NAVY Parachute Traveling Bag, but this one has no stamp and irregular side reinforcement parts, making it a rare piece. It may be a civilian-made item, but the details are unknown. The size feels slightly smaller and more user-friendly than a typical US Navy traveling bag. 【Color】 Olive 【Size】 Width: 48cm Depth: 23cm Height: 37cm Handle Length: 50cm *Please allow for some margin of error. 【Condition】*Junk ・The zipper elements are missing, so it only closes up to about 67cm out of a total length of 87cm. ・The slider easily comes off from the missing part (can be reattached and used). ・Small scratches on the bottom (images 7 and 8). *Due to the zipper damage, this item is being sold as junk. Thank you for your consideration. *Please purchase only if you understand vintage items. *I try to describe the condition of the items in as much detail as possible, but the perception of damage and stains varies from person to person, so please judge based on the product images rather than just the category and description.
