Back in 97 I found myself in the Chad archive on official bussines looking out data to support MRA4. Looking through piles of paper and with a bit of an interest in the Avro 730 I kept a close eye out for any references. Pickings were slim, but I did find a short memo which made reference to " an inspection of the full scale mock up of the Avro 730 on Woodford South Site". I know the Woodford photo store was lost in a fire, so I guess it's not suppriseing that photo may not exist but there is one well known heavily airbrushed picture which I've always assumed is a model. Just maybe?
