Matthew.
Where you point out that Morel and Bosman do not metion bellcap that is right and I must stand corrected.
I must therefore make my apology to all for this was a mistake on my part, however I must point out that it was not intentional nor indeed was it to mislead.
Where I did mention that C.-van-Driel Murray did refer to these things as bellcaps it comes from the same publication that you have used to explain the Velsen beltplates. It has to be said that where none of us are perfect in our postings or complete statements, I have to point out that without trying to be rude in any way at all there is a bit of inaccuracy in some of your own explanation about these Velsen plates.
Then where you refer to the washers being simple discs punched out of sheet brass, their slight dishing due most likely to the hole being punched in the centre one must consider as being conjecture or opinion on your part.
Also you say that like Matt Lanteigne you are puzzled by the claim that it takes less effort to peen a rivet with a bellcap than a regular washer, then the only way this could be clearly defined other than making and useing them to gain such experience of them would be under laboratory conditions with specialistic equipment.
Then where you say from not having tried these things that your observations cannot be conclusive, would it be coorrect to say that they should be discounted.
