Richard, F4WCD/ZS6TF has found this brochure ” Proof of Eddystone Supremacy ” dated 1934 which lists Testimonials from Stratton customers world-wide (including some very exotic places), stating how pleased they are with their purchase of Eddystone All Wave receivers. The back page has a list of 105 countries which have purchased Eddystone receivers. I have filed is in the Technical/Technical Information folder.
