How do I find this will?

[Kit]

Merry put me onto the Death Duties Index on FMP.

I've found the death of Wm Emett, husband of Christiana Emett, nee Taylor and I'd love to find his will, and his death actually.

Now I know he died in 1840 from the index but the location of the will is not clear to me. It says PCC and Country Courts. It is not the Prerogative Court of Canterbury as the will is not there. Where else should I look?

The FMP entry is:

Wm Emett
