    In the absense of a correct Martin Baker MK.1B or 2B seat i was happy to acquire this 1950 dated MK.1 from a fellow forumite (cheers Ian M) after putting out a wanted request. Very early MB seats are becoming increasingly hard to find, and it would appear that the only main difference between this one and the 1B are the footrests (telescopic on the 1B).

    Since this photo was taken it has gained a few missing items and there's still more in the pipeline to come.

    Wyvern

    Like most aircraft the Wyvern shared some parts with other types. But when these items come complete with some Wyvern provenance it makes them a bit more relevant.
    For instance this emergency hand hydraulic pump was found by another forumite (thanks Warren) and still has its 'REPAIRABLE' tag. It was removed from WN326 (which incidentally was a Suez war veteran) on ?.4.57 whilst at Fleetlands for modernisation as it was leaking internally.

    Another item is this AYF antenna that was originally fitted to the underside of one of the horizontal tail surfaces. Acquired from Robert B (cheers Robs) it was removed as 'UNSERVICEABLE' from VZ765 when with 813 sqdn on the 28/8/57. Incidentally VZ765 had a rather undignified ending, as on the 25/3/58 it suffered a partial undercarriage collapse whilst landing onboard HMS Eagle. With the Wyvern coming to the end of its service career it was ditched overboard into the sea three days later.

    Its funny how much these little tags add to the story and interest in the parts themselves. I have several Hornet parts with "serialled" tags too.

    Its nice to see your making progress on these projects. Good luck with them and it was lovely to meet you at Cockpitfest and have a look at your project.

    Totally agree. Those tags and the information they contain are history themselves.

    Wyvern

    Rear strut which formed part of a MK.8 rocket launcher from VZ795. This photo of WN324 shows the standard Wyvern arrangement of four rails per side (eight all together), two on the inner wing just outboard of the main undercarriage and two on the outer folding wing. At the rear of the strut can be seen the sockets for the electrical connections.

    Wyvern

    Outer airbrake release mechanism (incorporating a Mk.1A bomb release) from one of the airbrakes that was mounted in the top surface of both outer wings.
    This one is labelled as coming from VZ777 and was quite possibly removed sometime during its use as an instructional airframe at RNAS Bramcote. According to the book 'Fleet Air Arm Fixed Wing Aircraft Since 1946', VZ777 was used entirely as a trials and evaluation airframe (it was the first S.4 to land on HMS Eagle and also made the first mirror deck landing on HMS Illustrious). It finally arrived at Bramcote by road on the 11th September 1957 - but was broken up there during March 1959 after some eighteen months of use.

    Wyvern

    Contra-rotating unit from the front of a Python engine, minus propeller blades. Just under five feet in length and weighing around a third of a ton, it was acquired with the help of Mike Eastman.

    From left to right it consists of propeller pitch piston and cylinder - front propeller hub - translation bearing - rear propeller hub - propeller brake housing - drive shafts and oil tube. The oil tube running through the centre of the drive shafts supplied oil to the pitch piston, to simultaneously change the pitch of both sets of propellers via the operating links and translation bearing.
    This one is said to of come from VZ795.

    Fascinating thread and fascinating subjects, especially the Wyvern. Always intrigued by the Wyvern with memories of watching them at Ford in the early/mid-fifties when, I think, a trials squadron was based there using the runway as a simulated deck. I can remember steam catapult take-offs.

    Very nice find but struggling to see how it could have come from VZ795? Doesnt tally with where something like that should be found in relation to the extent of the excavation i.e. at the bottom of the hole but the dig only went down to behind the cockpit.

    Thanks for the kind comments everyone.

    Jon H - If it is from VZ795 i can only assume it was shed on impact i.e. not quite a vertical entry. The point at which it has broken off is apparently a weak point as i have a pic of a crash landed Wyvern on deck that has broken at roughly the same point. And it does have quite severe distortion to the hub holes for the blades. Nice piece though.

    charliehunt - Thanks Charlie. I can only envy you on actually watching Wyverns when they were active at Ford. But i don't know anything about steam catapults taking place there though. Stream take-offs certainly

    Is this the same unit that was on display at the Tangmere museum about ten years ago?

    Yes i presume it is.

    Would be nice to find at least one of the 'dinged' prop blades that were recovered as well, to display with it. The closest thing i have at the moment is about twelve inches of one propeller tip.

    Wyvern

    As per post #47, a draw full of instruments gleaned from the schedule of spare parts and which were only gathering dust has prompted me to have a go at making a pattern of the left side panel whilst i continue looking for the real deal, but bear in mind this is my first ever attempt . Armed only with a copy of pilots notes and pictures from a reference book, and knowing i would make mistakes i decided on using a piece of 6mm MDF as a starting point as it appears a similar thickness to the original, and also meant i'm not out of pocket should i c*ck it up.

    Hi Rob,

    Panel looking good, to assist on the dimensions, could you not get access to the FAAM example or are the layouts completely different?

    Regards,

    Tim

    Rob that is a great idea....I used the same method...its useful
    for making a mud map so ,if you have various cockpit photos(they dont seem
    to ever be from the direct front) you can closely match up the various
    angles for a pretty accurate representation.
    Cheers Mike

    Cheers Tim . To be honest i'm not sure about the dimensions of the TF.1 panel but the layout is completely different to the S.4. And even if they were good enough to give me access to the cockpit of VR137 the other stumbling block is the 360 mile round trip to the FAAM and back again. But we will see.

    Thanks Mike . I had vowed to not go down the made-up panel route but as the instruments were just sitting there i thought why not.

    But one things for sure though, as someone said to me recently your biggest critic will always be yourself. It took me ages to get the little ally bracket for the RATOG pushbutton to a standard that i was happy with.

    Bruce, i'm aware its different but its still relevent as the Wyvern used two different Machmeter's. Type MK1.A 6A/2194 as pictured and the MK2 6A/3384.
    But yes i would still be interested in the latter if you have one reasonably priced as well as the radio altitude indicator.

    Will PM you.

    Just thinking out aloud, was the Wyvern unique for a British prop driven aircraft in having a machmeter?

    Travel costs are a major issue these days, no matter where you live - I think this is the first year that I haven't gone to any air shows or visited any museums.

    Great project Rob, I remember suggesting a cockpit mock-up to you ages ago when you seemed less than enthused about the idea - glad that you have actually gone ahead with it.
