Back in 2017, I noted that I had acquired an anonymous chronology that seems to be Barbeu-Dubourg's ‘Chronographie our Description des Tems’ of c1753.
Recently, my colleague Sarah Mercer, Special Collections Project Officer at the Royal College of Art, very kindly made some excellent scans of the pages.
Here is a link to the Google Drive folder where they are stored. Each scan is about 14,000 x 10,000 pixels.
