It is interesting to me to compare the Daimler rad, with cast side cheeks and multiple tie-bars with the brass radiator on our 1916 Dennis, which is barely held together at all.

That radiator is sheets of brass soft-soldered together. The photo shows what we found chasing a leak. We removed the outer plate that the mounting trunnion was riveted to. The rusty mess is the backing plate for the trunnion rivets. It wasn't doing much...
So, where the Daimler has castings and tie-bars the Dennis has a top and bottom tank made of brass sheet and then then a box (made of 4 sheets) joining them but not soldered to the core (probably wise).
No wonder we spend so much of our time chasing leaks. That photo was the result of an investigation based on "Hang on, there shouldn't even be water in that part of the rad, let alone leaks"
