Thanks Bruce. That certainly does seem the obvious answer, but would electronic equipment of this kind really be placed in the wings? I would have thought something like a radio altimeter would be in the fuselage freeing up as much space in the wings as possible for fuel tanks. I’m probably wrong, of course, but I just wondered.
That’s great, thanks Bruce. Presumably this will be on the underside somewhere then? Whereabouts is the radio altimeter located on a Comet 4? I must go and have a look at the aircraft. I don’t recall seeing a fibreglass panel, although if it’s been well painted I probably wouldn’t spot it on a casual inspection.
Here’s a close up of the number. It’s been engraved by hand and is not very clear, so I’m prefectly willing to admit I might have some of the letters and numbers wrong. I hope this combination means something to somebody.
Good point!
Thanks guys – interesting posts. Fibreglass does suggest a dielectric panel, but for me that normally means a nose cone. I can’t think of anything that might have a flat panel of radar transparent material. It may well be that the GAF stands for Government aircraft Factories, but I would be surprised if we have a random Aussie panel (although stranger things have happened).
I’ll try and get a clear picture of the numbers, just in case I’ve misread them.
Re-examination of this panel indicates that it is made from a thin sheet of what appears to be fibreglass. The metal framing has the following marked on it: GAF 5RO L[or 1]AND / No 1.
Any ideas? Hopefully a fibreglass panel might help annrow it down. As always, any suggestions or comments are most welcome.
These are indeed Comet engine door hinges, and match exactly with the hinges on one of our doors, as per the attached photos. Thanks everyone for your help in identifying these – it’s much appreciated.
FoxVC10: Is 6M only Nimrod, or would it also apply to the Comets operated by the RAF? These may well be Nimrod (in which case we’ve collected them at some point in the past in order to have spares for our Comet) but it does make me wonder if they might have been for military Comets.
Incidentally, is the number 6 a manufacturer’s designation for the Comet and Comet parts? Are such designations listed anywhere? I ask because if it is possible to access such lists anywhere, it would save me asking fool questions on this forum!
Thanks loads for this, guys. I suspect they’ve been here since the 1990s and from the collection we have, I strongly suspect Comet as a contender. I’m sure I’ve checked the undercarriage doors, so I don’t think that is a possibility, but I’ve not looked at the engine doors. Clearly I need to have another look at the Comet.
If I find a match, I’ll let you know.
I’ve now managed to remove some of the white paint off these objects to reveal the numbers underneath. I hope someone might recognise these and be able to identify the objects as a result. As you will see from the first image, four ‘hinges’ are identical, with two slightly different.
The four are numbered: 6 M 4EC 535 ND
R1R
The other two are numbered: 6M4 EC 529 ND
R1R
Any suggestions would be most welcome.
I had a look at the spider this morning. Sadly, the face is too badly corroded and no numbers remain. I don’t think it would be relevant anyway as it fits the type 5 shaft, but it would be nice to have anumber just to confirm this. Unfortunately, it’s not to be, sorry.
I’ll have a look at the spider next week and let you know, although I think I’ve so far failed to find any numbers on it. It does seem to precisely fit the No. 5 prop shaft but, as you say, with the mix of components we have I can’t guarantee anything is what I think it is. However, the corrosion on the spider seems consistent with the prop shaft and other parts, but not the cylinder. Nontheless, I’m happy to check and get back to you.
I worked at Bawdsey during the war. None of us wore uniforms and no one knew it was the place were we did research, it was all a secret.
Thanks very much for your very interesting posts, Lois. May I ask what work you were doing at Bawdsey? I ask because the Bawdsey Research Station left on the outbreak of war and I would have thought there would only have been a handful of civilians left there after that. It would be fascinating to learn more about the no-doubt extremely important work you were doing.
Dairwin, thanks very much for this. It does make sense and we wondered if the cylinder was from a different prop to the blade as it seemed to be in much better condition. Most of the parts seem to have come from a wreck recovery, judging by the levels of corrosion, but the cylinder has no corrosion at all.
Thanks for all the responses, ladies and gentlemen. I’ve had another look at the blade and it is indeed a P55262. I think the stamped number actually reads DP55262-3 and is also numbered blade No. 3 elsewhere.
I’ve also measured the external diameter of the propeller shaft and it is indeed 96mm. Thanks MerlinPete. There are indeed some unrelated Griffon parts (mostly gears) which I think may be what has caused the confusion. Clearly, these parts are not linked to the propeller.
So, what we have here is a de Havilland bracket propeller type P55262 as fitted to an SBAC No. 5 shaft. Am I correct in thinking this? If so, presumably there is no way of tying it to a particular aircraft type and it could be from any of those on Anneorac’s list and more? Sorry for summarising the previous posts, but I am no propeller expert and want to make sure I’ve understood everyone correctly.
I’ve added a few photos of some of the parts we have which probably tells us nothing new, but I post them here just in case they are useful.
I’m still trying to identify this de Havilland braket propeller. Can anyone tell me what information I would need to extract from it in order to identify the propeller type and hence what it might have been fitted to? I am assuming that the numbers given in previous posts are not sufficient or I’m sure someone would have come forward to say exactly what type number this prop is.
If anyone can tell me what they need to know to identify it, I’ll do my best to provide the information and, hopefully, we can get this propeller pinned down.
