Kirk, I have found a reference to the Halson model 15 in an April 1937 Radio Today magazine. I am attaching a pdf image of the page. That still doesn't get us a schematic or verification of the tubes used, but at least we can rule out it being manufactured for another outfit. I'll keep plugging along. I love a good mystery. Holmes
