This is one of a number of radios which belonged to the late Ron Griffiths which were given to me by his widow in 2013. Ron was was an engineer, working for himself and making parts for other firms. He made some items for the Pastorelli firm - brass cases for surveying equipment that is used in tropical climates - and also brass parts for Cambridge Instruments.
The white circular disc on the aluminium chassis has the chassis number A346.
Martin J. Pratt who is a Director of R&M Rentals Ltd recently contacted me to say that his granddad Robert J Sprules who worked for Bush before and after WW2 designed the circuit for this model. Sadly he passed away in 2013 but was still repairing the odd TR82, he was 92. Martin has a number of working examples of the TR82.
