Chevrolet 1533X2 30-cwt trucks

I think that the top tubes of the bush guard are both curved, even though the angular bumper version has the bush bar mounted on the central straight section of the bumper. I've checked my references and it looks like the vast majority that I can see from the right angle to discern their shape are curved. There's a couple that look straight, but could just be the angle. Some have rotated so the curve is in the vertical plain, not horizontal. Also found a couple that have no bush guard fitted at all, which I haven't noticed before. I've learnt the hard way with these trucks not to draw definite conclusions, so I'm comfortable to say that the vast majority are curved and there could be some that are straight!

Maybe the curve was introduced so that when you crested a dune at speed and encountered a camel, it would be deflected to either side, rather than coming straight up over the bonnet and into the back of the truck.

The first photo shows a Y Patrol truck without a bush guard and the 2nd photo shows the bush guard top tube rotated, showing the curve in the tube. Interestingly all the rotated tubes show the curve going up not down. I have no idea if that is significant.

Dave Ashby has very kindly photographed and measured the bumper brackets on his 1542 truck which are the same on the 1533X2. He has asked me to post them for him. There are 6 photos and 1 drawing with dimensions attached here and on the post below. Note on photo 4 and 5 there is a smaller near vertical rod that attaches to and supports the bottom of the grill.

Thank you Dave for providing the photographs.

Colin Alford, I'd be really interested to see if there is anything on these brackets in your manuals, and also anything about the steering gear for the 1533X2 and 1542/3 trucks in your Major Assemblies Catalogue. The last pieces of information needed for a complete overview of the iconic LRDG 1533X2 truck.

Please see these extreme close-ups of the transmission-driven tire pump control lever and hose connection point on the left running board of the 1543X2 and the 1533X2.

Colin,
That's fantastic!
Never thought I'd see this in such detail. This looks like there was no hole in the cab floor to activate/control the PTO pump, just this simple pullout lever to engage it. Or maybe both?
The question remains for me, what other details have you got of this series of trucks.
I posted photos of the 1542/3 bumper brackets kindly provided by Dave Ashby, which shows a modified grill where the bumper brackets come out the front panel. The modification gives a larger opening for the military style bumper I presume. Really keen to see any details of this if you have them. I've checked my LRDG 1533X2 photo's but can't see whether this detail is on the trucks, its just an area that was hidden by the bumper or stowage. Any help massively appreciated.
