Wanted: British Sand Channels

[David Dunlop]

I would be inclined to err on the side of caution, Philippe.

All we know for certain, looking back at 75+ year old photos, is that two different size channels existed. Why, is very much still unknown. The other interesting thing here is that all these photos are of one type (weight class) of vehicle. That suggests both sizes could do the job for this one type of vehicle.

One possibility for this showing up could be the bigger channels came first. They worked but may have been heavy and difficult to work with. Or, smaller ones developed to save steel or costs.

What would be interesting at this point, would be to find photos of a different weight class of vehicle equipped with channels and see if two sizes show up there as well.
