The most innocuous of tumbles onto a very soft carpet this morning and this is the result. Strings have been removed and I've not even attempted to look any deeper. It's back in it's hard-case waiting for virus lock-downs to pass and then I can get it to a luthier for a professional opinion, and hopefully, a fix. It's a Manouche Modele Jazz. Highly annoyed with myself - although I still don't know what happened, other than I heard it fall, turned around and this was the result.
