This is a 4 oven version of the Aga 47/10 (4710) or Model C range cookers and was Agas first 4 oven range cooker. I don't have an image but to identify it has a towel rail that fits between brackets that are integral parts of the hob. It was produced between 1936 and 1941 and withdrawn in favour of the 'Aga' Standard range cookers that are common even to this day.
Matthew is from a farming family near Bath and a graduate of King's College London who decided not to follow the 'standard' path into banking or the law. He has been working with these fabulous cookers in some form or another since 2003. Matthew runs Blake and Bull from beautiful Bradford on Avon, near Bath. Alf the golden retriever makes sure the working day finishes at 6pm sharp - dog walk time!
