While looking at the Devon Records Office site, I noticed this...
'This first batch of digitised parish registers were released online on 30 May 2014.
Note that none of the digitised registers from North Devon Record Office which have been supplied to Find My Past have yet been put online....We have not been informed by Find My Past when further Devon parish register images will be added. We assume that family historians and others will eventually be able to access high quality images of the majority of Devon’s parish register entries online.'
So, it sounds like FindMypast have more records ready digitised but not yet released.
