Well spotted.
On a copy of the dial face, I drew in the hour lines extended back
towards the centre. Most of them convert at a point consistent with the
knife-edge style that can be seen on the gnomon; likewise the hour lines
for the hours closest to noon are slightly offset in a way that would be
expected from the secondary styles created by the bevelled edges of the
wide gnomon.
So, the dial was crafted quite precisely. The sides of the grey area
don't match that precision, which supports your suggestion that it is a
repair.
Cheers,
Steve
