    I hope no-one mind me dragging this post back up but I’ve been unable to identify this panel and would be grateful for any information or suggestions. The hand-rail (or whatever it is) would seem to be quite distinctive. There’s something about it that makes me think Shackleton, but I may be completely wrong in this.

    Any helpful comments would be greatly appreciated.

    Ian.
    I’m not convinced all those parts match. It appears to be a Griffon prop shaft, which is unlikely to have been fitted to a bracket prop. What is the outside diameter of the splines?

    Pete

    The external diameter of the splines is 67mm. Does this help with identification?

    You might be right Pete. Not included in the photo are some reduction gears that I’m pretty sure are Griffon. The prop shaft, however, I’m sure is Merlin. It is the exact dimensions of the shaft fitted to our Merlin engine and is between the diameters of the two Griffon prop shafts on our Shackleton engine.

    I’m pretty sure it is a de Havilland propeller, if only because it is covered with de Havilland Broughton inspection stamps (thanks Bruce!). There are a few other numbers: the propeller blade has the number on the root mentioned in my previous posts which I now think appears to be DP5526353. The casing round the hub is numbered DH514714 and the propeller reduction gear drive coupling has a number GN19940.

    The de Havilland Broughton inspection stamps are numbered DHB 4, DHB 14, DHB 82, DHB 108 and DHB 147.

    In the hope that it might help, here is a general view of this propeller. I think it is a de Havilland bracket type constant speed, but I have no idea about the actual de Havilland type number.

    I am very keen to try and identify the type of propeller this is and, if possible, the aircraft type it would have been fitted to.

    Cheers – thanks for that.

    Does anyone have any ideas about this propeller? I thought the numbers might identify it, but is it possible there are other numbers I’ve missed which would provide that crucial piece of evidence? I can’t believe with the knowledge on this forum that no-one is able to say what this prop is off.

    A bit of Googling has eventually revealed that these are both Lindberg kits.

    According to the Dunlop website, that size fits a Belfast. These particular wheels could be from something else, but they are potentially from a Belfast. Check for a part number – if the have the part number DR3223T then they are definitely Belfast.

    I’ve not, Mark, but thanks for that. I’ll give it a try.

    Thanks, but I’m looking for an image of the cabin interior, not exterior shots of the aircraft, of which there are plenty around and easy enough to find on airliners.net and elsewhere.

    Richard,

    Thanks very much for that. So, a possible winch gearbox. Anyone any ideas what it would be from?

    Dave,

    Thanks for that, which makes sense. I calculate the length of the quarter wave to be approximately 43cm which if my maths is correct would give a frequency of 174.3 MHz. If that’s right, does that give any more indication of the function of the aerial?

    Dave,

    My bad! Thanks for that. I’d always understood each dipole was a half, not a quarter wavelength, but there you go. I’ve definitely learned something new!

    If this aerial is marine band VHF for aerial use, is it perhaps off a Shackleton?

    Thanks for the posts. Ignoring the curved bit joining the two dipoles together, each dipole measures 45cm long. From that I figured a wavelength of 90cm which I calculate to a frequency of about 350 MHz (well, actually 333 MHz).

    And, no I’m afraid it’s not a V-beam aerial! 🙂
