Some further thoughts on Paul Bardunias' idea:-
Thinking further, we may indeed be able to reconcile the profiles of Connolly/Sekunda with Dr Jeromonides description and sketches...provided we ignore the sizes given by Connolly ( and he doesn't have any figures for the rim anyway.
In the attachment, I have 'extended' Dr J's fig 1 to show a swelling as the 'shoulder' sharply curves around, with a 'guesstimated' thickness of 3-3.5 cm, tapering back to 2.0 cm for the 'flat' part of the shield going toward the centre.
This accords with the dimensionless profiles of Connolly/Sekunda, while preserving Dr J's measurements, thereby reconciling them.
That leaves only the problem of Connolly's dimension of 5 mm(0.2") for the centre, against Dr J's 20-25 mm (3/4,-1")....and that must surely be a mistake, or a wrong guess.
