the curious case of the mysterious sleeping bag!

[coleb87]

so i found a sleeping bag in my closet, which was OD green and mummy style. it had just one tag sewn into the liner. this tag gave me the model number "dsa100-77-c-0776"
curious to find out about the sleeping bag, i searched on the web,to no avail. i suspect military surplus, but dont know how old it is. if someone knows,please reply. i will post pictures as well!
