I've just acquired another tenor, a Gold Tone TS250R but it will be set up for Irish trad playing, GDAE octave down from a fiddle. This came fitted with a Plectrum neck which I've removed to refit the original tenor neck. This has been slightly butchered by the previous owner to fit the hoop, but is servicable if anyone wants to try and use it for a frankenbanjo.
In the UK, besides trad jazz the other place you find plectrum and tenor banjos is so-called BMG groups or orchestras, Banjo, Mandolin and Guitar. There used to be quite a few of these when I started playing in the '70s but they've mostly died out.
