Dove and doncaster heads.

[Bickerton, Roderic (SELEX GALILEO, UK)]

The short 6 cannon bells should be differently commented to normal high
cannons.
They represent a significant change as they allowed the bell to be
mounted much higher without a deeply cut stock. Allowing faster turning
more responsive hanging. They are also very different in appearance.
I believe they should be noted, not just passed over as having 6
cannons.
I think short flat topped cannons represent the important development,
and that 4 cannon Doncaster heads are just a fairly irrelevant tweak of
the idea. 
I think the "Doncaster" classification should be dropped in favour of
"short cannons" and recording the number, as it would appear that
"Doncaster" is just 4 cannon variation. 

As an aside is it thought that the high cannons date back to rope
lashing, but bell founders did not change tradition as iron hanging
became normal, at least until Victorian engineers started to notice.
