I've just discovered, by accident I have to admit, that the Ancestry images include the 'Transcript Book' front cover page. I've never seen these before on the FindMyPast version.
The front cover page includes the signature of the person completing the book and the date. I've been having a look to see if any of my family members completed the book for their village, but none so far. I'm starting to suspect the work was done by officials from outside the locality.
To view the cover page, firstly access the image viewer from any record in the location of interest. Then change the page number to '1'. That should then load the first page which usually comes up as a cover (but sometimes a blank page).
