Arguably https://www.alexander-dennis.com https://www.dennis-eagle.co.uk/en/ You can still buy a vehicle with “Dennis” on the front.

I visited the Dennis factory in the late 1980s and it was much the same then. I think that low-volume truck production might have changed less than you think.

I had the inverse problem. After I finished my course at university I hung around for the rest of the summer taking the fire engine (which has a central accelerator pedal and hand-operated brake) to rallies. When it was all over I rented a transit van to take all my stuff back North to start a PhD. It was as I was heading down my road, which runs straight out into the A4 near Heathrow, that I suddenly couldn't remember which pedal was the brake on a modern vehicle....

I don't know if you were replying to me, but you quoted my post so I assume so. I would never (well, almost never[1]) dream of using anything but an exact replica thread and fastener. What I was pointing out was that a correct imperial coach screw can be found inside the metric one if you peel it carefully. [1] The flywheel bolts on the 1916 Dennis currently have metric heads, but as they are prevented from rotating by machined flats rather than a spanner this is not a concern for assembly/disassembly. I used metric washer-faced bolts as a source of high-tensile steel of the right type and heat-treatment.

It is, but stated the way I did I feel it makes it clearer that an M16 bolt has 1/16" of extra diameter to work with. (If I ask you what the difference is between 5/8 and 9/16 isn't the first thing that you do to double the 8ths?)

When we needed some feather-edge coach bolts for the wings of the fire engine one of the club members (a famous loony) re-machined metric bolts. He used MNC, Manual Numeric Control, for the heads. He had a table of coordinates and dialled them in by hand on the lathe handles. M16 is 10/16" so I would imagine that you could find some 9/16 coach bolts hiding inside metric 16mm ones. M14 is slightly undersize for 9/16. And I rather expect that M14 coach bolts are rarer than 9/16. However M16 coach bolts are likely to be 2mm pitch, so I imagine that you would need to cut all the thread off of over-length ones to get a good thread. Alternatively, perhaps try the US, but again buying over-length and re-threading. https://www.fastenersclearinghouse.com/fastener-search=carriage-bolts&size=9/16-12&Cat1=PRM460D65E02814;&Cat2=FL3DCA0E45011;

At first I thought that the counterweight on the sledge wasn't moving (it moves forwards through the pull in competive pulling) but on a re-watch it is. So that's quite impressive.

"We have a pressure lubrication system, but you can turn it off once the engine is run-in as it is clearly a silly idea which will never catch on"

You might find contemporaneous oil paintings, I suppose. Colour photography was available at the time, so I would not want to rely too much on colour fidelity. Especially this long after the fact. There is a 1917 photo of a French Soldier on the Wikipedia page, interestingly: https://en.wikipedia.org/wiki/Color_photography

Maybe, I remember an Enfield Pageant in the 80's where the field was like a mud pudding, with a dry layer of turf over a squidgy base. Low gound-pressure vehicles didn't even notice, but those of us on narrow solids were completely stuck. But: The simple application of a Landrover was a lot less bother than putting chains on. Not that seeing chains in action isn't an end unto itself.

Just an opinion, but they are original, and you are unlikely ever to need to use them, so I would keep them, patina and all.

So, how can we get them both on the 2022 HCVS Brighton Run? (2021 is probably optimistic)

If you turn on captions it tells you where every scene was shot.

Are you following the 1908 Dennis thread? Ben is building an entire radiator from scratch there, too.

It's like a Karrier Cob that's gone terribly wrong 🙂

I assume that you have seen Ben's 3D-printed radiator patterns?

Ford has a big research centre in Aachen. Perhaps there is a connection.

What you need is a hydraulic rivet squeezer 🙂 (I am surprised that you haven't made one?)

Off topic for this thread, but here is how it got fixed:

Isn't the whole thing probably an observation post? So the pigeons are just the 1914 equivalent of radio aerials.

How mildly insane!

How does the top tank attach to the radiator core?

I think it's legitimate enough, there are even special files for the job: https://www.amazon.co.uk/Bahco-1-104-14-3-0-Lathe-File/dp/B0002YQ5PI

Next day from Amazon, even. Though probably not in Imperial Sizes.
