God Nicko, I feel like a dog coming back to its vomit! Still, before Delta carries us all away it is necessary to keep history preserved, which is a greater Mistress. In respect of Highball material, a positive identification was made between remains of mechanism found in Narromine NSW and original drawings found in the RAF Hendon Museum archives and cradle remains held at the dH Museum in Herts to confirm absolutely the setup of Highball Mosquitos. A lot of detail dimensions were taken of ex Narromine remains held in NZ and Australia and the UK material to allow a CAD reconstruction which remains on the list of things to do, after surviving 2020 & 2021. Hopefully there will be no massive asteroid strike on planet earth in 2022, which might allow this task to be completed.
