Left and above. Two views of the recovery of 823. The tail section was not salvaged.
Below. Two images (courtesy of Gina Wilson via Friends of the Wessex 31) which purportedly show Wessex 823 being used as a template to map out the proposed Life of Type Extension. This LOTE was to replace the single Gazelle engine with two Rolls Royce Gnomes, similar to the RN Wessex 5. The project was abandoned for various reasons. The left image shows the nose of an RN Wessex (sand coloured) being mated to the fuselage of 823.
