Saving in Latin1 with emacs

[David Rasmussen]

I have a file containing text in some weird encoding. 'file' says:

Non-ISO extended-ASCII English text, with very long lines, with CRLF, 
NEL line terminators

Basically, I want to convert this text to Latin1. I have tried recode 
and iconv assuming the text was utf-8, but they both claim that it is 
not utf-8. Maybe it is a mix of several encodings? I don't know.

But my idea is this: emacs seems to be able to _show_ the file just 
fine, regardless of whatever encoding it is. So I'm thinking: It must be 
able to save this file in Latin1.

How do I do that?
