Reminds me of a translation job my wife and I did. This was before google and any kind of translation engine. It was just a small text to be included in a CD case. But there was a thorough listing of the instruments played by the artist: about a dozen different kinds of trumpets. Even though our command of the English language is quite good, we were at a loss. We could not just write that “He plays a trumpet, a trumpet, a trumpet, and a trumpet”, and no dictionary we had access to was in any way helpful.
So we got pictures and information on all those “Trumpets”, got our hands on an English book on musical instruments, and painstakingly identified each single instrument. It took us days to translate a single column of text, but at least those trumpets had their proper names.
