That's what it was, Pip. There are also eight string versions, which are Mandolin/Banjo hybrids, and six string Guitar Banjos.
I would have thought that there were very few performers who were more English than George Formby and Gracie Fields. They were far folksier than any mead-drinking, cittern playing revivalist playing part-composed Cecil Sharp-ised rural ditties.
