Gary,
Were there any fuel/water tanks in there? I know at least 1 of Jeff's engines should have had a full set of tanks (water+diesel), plus IIRC another standard sized diesel tank & one outlandish big one (may have been water actually).
In fact, are those photos the sum total of the contents of the container, or are there other bits unpictured? Because TBH I'm pretty sure I physically collected more than has been shown there.
Cheers,
Ade.
