The Berne specimen seems to be quite popular, as largely divulged in the Internet. It is also, for example, in Clephan's work 'An outline of the History and Development of Hand Firearms' (page 47). I also happen to have a picture of it, myself.
But again, i may obviously be labouring in error, and confusing the whole thing.
