Yes, I've included all the pictures.
It appears that case AG21049867 is similar to my situation, as there seem to be no signs indicating the restrictions at the point where Pursley Road meets Page Street.
It seems that in the case AG1410210A, it was suggested that the permit bay signs on this road might be insufficient, and case 2130378354 appears to indicate:
"The Authority say that the street was subject to event day restrictions, because of a match at Saracens rugby club, and that signs warning of the restrictions did not have to be placed in individual streets, but only at the entrances to the restricted zone."
