FS2004 Scenery object "Hesco Bastion"


I am in the process of making a military desert airbase in FS2004, and was wondering if anyone has made or come across a scenery object called Hesco Bastion ?
I have searched the web to see if i can find any but no luck so far, I would appreciate any help or ideas if possible.

Many thanks
Cheers Pakmac for links,

Some really good pictures. I did find a google sketchup model of one but will keep looking to see if i can find a Gmax or mdl version.
