Gentlemen:
A short article in the Mar 03 issue of Flypast Magazine indicates this is a composite a/c assembled over a 25 yr period. The fuselage is that of LZ844 which was indeed a Mk V and the engine area and prop assembly is taken from an un-named MKVIII.
The four bladed prop, the longer nose profile, the 12 exhaust stacks coupled with the "universal" filter at bottom area of the cowling indicate the Mk VIII front and everything else from the firewall back indicates Mk V .
LZ844 was operational with 79 Sqn RAAF coded as UP-X.
