Are you looking for it on Ancestry?
What you've found is the sentence; the legal.judgement. (perhaps a challenge or something not legally correct with the will) sharing link
The actual will is in English but is indexed on Ancestry as Guilielmi Blore sharing link
(Edit, horrible scan on ancestry though. Would be better to download from TNA)
(Edit 2, can't read much of the will on the Ancestry scan on my phone but 1) it's not the usual form for a will (perhaps why it needed juducial review) 2) can't see ref to City of London but it will be there somewhere . It may be where he was when he wrote his will, not necessarily where he was when he died.
