Thanks to a little searching, I found there were some additional volumes of Ruffhead continued to 1786 (25Geo3).
There as in 1786 a new edition by Runnington which was extended to c. 1800
https://en.wikisource.org/wiki/Template:Ruffhead_volumes has links either to Wikisource Index pages, or to external scans.
Did you pl;an to run OCR on the later volumes at some point?
