LRDG Ford F30 Offset air cleaner

[Charlie Down]

Researching the LRDG Ford F30 and noticed that photos showed the air cleaner further forward than usual. Did a search on here and found a post saying the original filters were inadequate for desert use and Ford developed a Heavy duty cleaner that needed an offset inlet pipe to fit into early Ford Cab 11 and 12 models.
The part number is C01Q-6765D, but there are very few photos or information on it.
Are there any more photo, diagrams, manuals showing this item?
I've included the available side and bottom views previously posted (sorry can't remember the name of the poster) as well as a photo of a LRDG truck showing the arrangement.
Thanks in advance.
