I found a Little Spitfire horn only, no base, a few years ago and made up a driver for it as shown, sort of faintly reminiscent of Magnavox, using a small PM speaker and some plumbing fittings, on an oak base. There's an output transformer in the base also so it connects up just like a high-ohm speaker. Here it is with my 1924 Radiola III and reproduction radio battery. I really like that C/E radio!
