I always thought that it was from the 19th century, but on reflection I think it may be older, maybe 17th or 18th century.
There is no cover to it and no identifications to its date, it looks like the drawings from a books appendices that have been ripped out.
I like the Moon engraving.
I took out some of them and framed them for my study a while back, probably shouldn't have done that :-(
