I used to have a hand cranked generator from an old phone. This puts out
exactly what you need. Think they are still available through gov surplus as
field telephones.

Try the Viking Electronics model DLE200 telephone line simulator box.
It's only about 5" by 2 " with phone jacks on it. It only cost around
$100 about 12 years ago.
