This manufacturer calls this its "Reference collection of vintage gear / Special emphasis on Western Electric". By all means explore the "Click for gallery" links. Their thing is to design and offer products that simulate the 1920s/1930s theater experience in home listening rooms. No surprise, they appear to favor triodes and efficient horns.
I hadn't seen the 16A horn before. Only one is required for stereo and I would not mind if someone gave me one.
