Wanted: British Sand Channels

[Philippe Jeanneau]

While looking for more information I came across this...

And wonder if the sand channel would be for a smaller vehicle... Seems quite a bit narrower than one used for a 30 CWT truck...

Based on the photos posted, Philippe, there are indeed two different sizes of wartime sand channels. The colourized photo shows the wide version. Note the large empty space on that set from the outer longitudinal edges of the channel and the outer rows of holes. Also where the upper edge stows and how the lower edge is situated below the top recess of the wheel well.

All other photos show a narrower channel with very little outer edge empty space and the channels when stowed, fit completely within the gap on the sides of the truck between the upper edge of the wheel well and the lower edge of the top reinforcing channel of the box.

Why there are two different versions is an interesting puzzle, but you at least now have proof they both exist and were both used in the same theatre, by the same type of vehicles. You are making progress.

I couldn't agree more, there were many different size vehicles in the desert, so it would make sense that there would be different sizes available to correspond to their size and weight... Your observations are spot ot. There is no doubt there were different sizes available and finally we have proof... It is quite nice to see an original piece... A first!

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.

Field Marshal Alexander's car in the Canadian War Museum has some mounted on the back and it may be possible for someone to get permission to photograph and measure them once the museum reopens to the public. This is an old photograph from 10 years ago so I am not sure where this vehicle is currently located within the Lebreton Gallery

Interesting photo, Ed.

I wonder if there is a correct way and an incorrect way to stow these channels on a vehicle?

On Alexander’s vehicle, the two channels are nested into each other and look at the big gap between them and the retaining bar that is supposed to secure them in place. At the very least they would make quite a noise sitting like that when the vehicle was on the move, if not get lost altogether.

When you look at the earlier photos posted, you see some vehicles where the two channels are cupped against each other and fit snugly into their stowage brackets in that manner. On the other vehicles, the channels are nested when stowed and have extra web straps added to hold them in place, with lots of extra space in the brackets.

Interesting.

All very interesting points, and very happy to see another photo of the smaller channels... It totally makes sense that they would exist, as did the larger size. As to how to properly carry them without loss and having them rattle their way down the road is another matter...

I believe that we were trying to ascertain the original dimensions of the larger size channels... While looking for this answer, I thought that one big clue would be in this first photo... If you compare it to the diagram, these should be as wide as the distance between C and B in theory, except...

1- We don't know if the truck in the photo has the bed in the diagram...

2- We don't know width of the channeling that surrounds the box...

But could come close... The difference between C and B is 15-1/8 or 384.17 mm which might just be the ticket and what my friends Chuck, Bob and I came up with...

As for the length, somewhere in the 81" or 6.75' seems in proportion...

I know there are some out there, but someone willing to help has to come up with the information...
