I think I might have them lying around, but do you
really need
them? Assembly is pretty straight forward. The pictures on the front
and back show pretty much how they go together. The most complicated
part is the tanker helmets, which have the ear flaps and the part that
protects the back of the neck. But those parts really only fit one way,
so a little test fitting should be all that's necessary.

I just found the box and it occurred to me that there may not actually
be instructions for that kit. You'll notice that the part numbers are
shown on the back of the box, next to the corresponding parts, making
the pics on the back effectively your instruction sheet.

Sorry, I missed the crucial detail in your post that the figures
came with another model. I'll scan the back of the box and post it for
you.
