Hi Pat,
The fascine was made of bundles of light wood, you could use the bristles from a Coco brush for this. If you have a look on Gordon's Cromwell site there are some good reference pics of the bundles and tubing.
Hi Jim,
If he was standing on top of the turret he'd be about 9ft tall lol, lol.

The driver had virtually no vision so the commander perched on top of the wood pile in order to direct the vehicle. Basic but it worked.
