My own copy of this, which is "third edition revised" has been annotated in pencil "by A.C.O." - that is only evidence for the assigned authorship I have.

There's a typo in the Greek in the main title - there's a nu in the place of an upsilon (so at the moment it's reading "paronsia" rather than "parousia").
Sorry, that's a bit of a picky point.

Thanks, corrected!
