The introduction of ASV21 occurred much earlier and was not a part of Phase III. It was introduced at late Phase1/11 approximately 1959 onwards. Phase III meant a complete airframe rebuild plus the changes included new nav and compass system, an additional position in the tactical compartment (2nd Sonics) The ability to carry the American nuclear DC plus a host of other minor avionics changes. (all the switches became grey and not black) And most importantly improved soundproofing, oh, and a nice creamy decor inside. Still b****y noisy though!
The Viper fit was a separate “upgrade” which eventually got rolled into the Phase III modifications, this is why it is often believed, incorrectly, to be part of the Phase III. These changes also meant that the engine generators had to be enlarged to provide the electrical power, this in turn meant uprated gearboxes etc, this configuration gave the Griffon its MK58 designation. Incidentally, Gatwick Aviation Museum have the last MKIII to undergo Phase III conversion, WR974, this was completed in March 1970.

Ben,

no offence taken, apologies if the reply was a little terse.
I was simply stating the facts. We would have loved to have received any of those airframes, however they are a commercial organisation after all. Plus with the problmes we have with the local council it may have made the situation more difficult.
I can also confirm that the “Jaguar” we have XX734 came from Aerospace Logistics. We were offered XX121 about 18 month ago, that offer has now been withdrawn. I have no idea why, again I assume that the company has decided to get more money for it. The Faygate yard does indeed belong them.

Beware !

I recently obtained an AP from Hendon, no problems, reasonable cost and timing was slow but OK. When I asked about another manual it turned out that what they thought they had was only the cover and separators but no content! They had no idea what had happened and that was the only “copy” they had. It was an AP for a radar so I asked Cosford if they had it, they get theirs from Hendon!

This is just a warning to say just because it’s listed it may not be any use.

By the way anyone know where I can get a copy of AP2890G (ASV21)?

Chris Ashworths book (THE definitive book on Shackletons!) does have a whole appendix on the Nomad.

This link is basically

a shortened version of the text.
There are also three accompanying photos showing the engine installation + the wing radiators.

Additionally there is some interesting info on this link (from the same site, thanks to Mo Botwood).

Shackleton Periscopes

There was more than one place to use the periscope on the Shack.

Mostly used to observe the bomb bay, one point is in the floor between the Flt Eng and the WOP. There is another at the rear of the bomb bay in the galley floor. The periscope itself is stored opposite the entrance door.

Props turned by wind… Funny!

Someones pulling your Plo***r! If you had any idea how much wind force would be required to turn the engines over from the props you’d be a little more skeptical. Of course it is possible, not sure how much more would have blown off the rest of the airframe by then. At GAM we lost the DA behind No.3 a few years ago in “hurricane force” winds, but oddly enough the prop blades didn’t move. Hand rotating the engine does it no harm ( either direction). In fact it’s part of our pre-start checks. Turning constantly for a prolonged period would not do the engine any good mind you.

The lens were fitted in place of the AI23 radar in the “bullet”.
If my memory is correct the bullet also had ballast in to ensure that the correct weight was in the nose. The AI alone weighed 225lbs.
The F1A’s were a lot faster than the squadron F3/F6 models.
TFF pilots would have great fun at the end of the day slowing opening their throttles as a squadron F3/F6 approached and then out running them!

It was a common occurrance to hear over the radio a frustrated F3/F6 pilot
cursing the TFF pilot.
