Spares
While idly glancing through the multitude of channels available to us nowadays I chanced on Discovery with a programme on building the Burgh tower in Abu Dhabi. They were describing the selection of the glass to be used to clad the building and the tests they were going to carry out for leaks after installation, first a static test by just spraying water on the panels and then a dynamic test by having a strong wind blowing on the test panels and the programme showed the device being used to create this wind. Lo and behold, a Shackleton power plant complete with contra rotating prop, (despite the voice over saying it was from a Lancaster ), just so recognisable as off a Shack, So if you need some spares, somewhere in Abu Dhabi there is a complete powerplant in working order or at least was when the programme was made.
Best of luck with your project, only flight in a Shack was back in about '63-'64 from Kinloss when I was in the ATC for an air test, memories are being given a chute, very confidence inspiring, and sheer terror as it appeared to fall out of the sky to find out they were doing stall checks. Other memories are of being at Biggin Hill watching a display by a Shack and having a low speed pass and a high speed pass described by the commentator as being identifiable not by the speed but by the amount of noise produced! Rather rude if possibly quite true!
