Why would they bother using fake figures, why don;t they just photocopy
the genuine product and then fake it, all seems rather strange to me.



And also the on-site guide, it seems.

Apparently genuine logarithm tables used to contain deliberate errors, to
trap forgers; and OS maps include things which are not there.

I can see that a slightly incorrect kink in the road isn't going to kill
anybody

but a deliberately wrong figure in a log table just might :-(
