The contents were:
Jelly Bar
Compressed Granulated Sugar
Grape Jam
2? Crackers (they were a complete mess, can't 100% tell)
2 Soluble Coffee Product
Cookie (I got no clue on what flavor it is, sorry!)
I was in complete shock opening this, expecting for jam to be completely exploded all over inside. Turns out, this is a perfect example as you can get for a 71 year old B unit

Nothing was rancid, the coffee is still powder, but the cookie and crackers have been flavor tainted by the can, and now just have metallic taste. However, the cracker still had a saltine cracker like taste, but not worth eating at ALL lol. The jelly bar is hard as a rock, and didn't try anything else.
