That’s great research Steve. Sounds like an ‘interesting’ character. Livestock as deposits on radios! Sounds rather desperate to me. Surly it would have been easier for the farmer to sell his own cow at the saleyards and use the money for a deposit rather than giving the animal to the radio salesman.
I imagine that Wylie wasn’t designing the sets himself. He was more likely building up radios from circuits published in Lamphouse annuals and similar publications and ordering all the parts from Turnbull and Jones etc. From the look of the chassis he may have been bending them up himself in his “factory”.
The Telerad deluxe bandspread looks familiar to me, I may have had the chassis from one at some point. From memory the under chassis construction was rather amateur. Looking at the photos of the deluxe on your website, it appears that it has no RF amplifier, which is a bit odd for a set with bandspread, the valve line-up is very likely to be 6SA7, mixer/oscillator,6SK7 IF amp, 6Q7/6SQ7 1st audio/detector, 6V6 output, 6U5 eye and 6X5 rectifier.
