Sand chains...

[Rolf S. Ask]

The picture shows a dessert chain (part of...) that someone came with at a MV-meeting this summer. He promissed to look for one or two complete ones he tought he had somewhere. He told us that it is a "dessert chain" or "sand chain", and it seems a bit strange such items surfacing here in cold Norway. The explanation must be that they was left in the vehicles (part of the standard equipment) when the CMP's was sold from Canada to Norway after the war, and then was laying around at some military work shops.
But I can not remember ever seen anyone of them used in any film clips or any pictures. Was this standard equipment in/on vehicles delivered to the dessert campains? How common are they? And anyone who can tell us abouth the use of them? Where they usefull at all??
