This appears to be from around the 1970s. It's a large TALON ZIP zipper, 1980mm long. It's deadstock. It's in good condition with no damage like wrinkles. The slider is on both sides, allowing it to be opened and closed from either side. It was probably used on the opening of something like a US military tent. I am listing two other identical items. This is a set of three items. I think it's very rare. How about it? Thank you. *Please note that shipping arrangements cannot be made on October 23rd and 24th.
