Marked with:
"Manufactured by Sigmund Eisner Co. under license granted to the U.S government by the Pioneer Parachute Co., Inc., Manchester, Connecticut"
"August 1957"
"..Wing Air Chute.." (We can't make out what it says before 'wing' and after 'chute' as its faded)

The metal plate on the backside of the pack that is connected to the metal bend tube is marked; 53C6922
The name ' Woo ' is written in sharpie in multiple places over the canvass / fabric.
There are multiple areas of fraying fabric, staining, fading, scratches and scuffs throughout. The adjustable straps have lots of discoloration and staining on them also. Please keep in mind that we are not sure how complete this item is and is sold as is.
The lighting of the photos sort of make the 'olive green' color of the pack a little 'tan?' looking. In person the color is typical military green albeit the fading and discoloration in places.
Not intended for purpose-built use.
No parachute is included!
Please feel free to ask any questions, thanks for viewing, have a great week!
