Can't find my old post?

[Nathan Ross]

It's title was something like "Need help about French translation".  A member that I can't remember kindly translated it sentence by sentence and Sir Duncan Campbell also posted his comments since it was about a kind of large bolt shooting device.

Do you mean this one? Addition to an old thread rather than a new post.

DB Campbell's translation job is here.

(I do not believe that Mr Campbell has yet been knighted for services to Roman Artillery Studies, but I could be wrong!)
