Chevrolet 1533X2 30-cwt trucks

In that left photo with the curved bumper, is the brush guard tube directly above it also curved to match the bumper, or is that just the shadows playing tricks on my eyes?

I think that both those trucks have curved brush guard tubes but possibly the one with the curved bumper is more curved.

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.
