Jungle Ordeal (7309-3) is another jumpsuit based card, this time in classic camouflage. Initial releases added a surplus Australian Jungle Fighter trench knife with gold painted grips, but most sets feature the knife in plain silver. The first release version with the Aussie style knife is immediately below.

Note the changes in the trench knife, from the same version found in 60s sets, to an all silver version, to the final version with a blunted tip
