    Thanks James. Interesting point about British prop aircraft fitted with machmeters. With the Wyvern i think its a case in point of the era's transition from piston to jet engines and also its uniqueness at the time as a type and its intended use. According to the pilots notes its max diving speed for the release of bombs and RP's was 500mph which equates to mach 0.66 (considerably less with a torpedo). Although i'm sure i've seen it quoted somewhere with this figure being exceeded.

      Here's a pic of the undercarriage position indicator i'm looking for at a reasonable price. Its a type D Ref 5CX/4204 (ebay pic).

        Wyvern

        Shown again for the benefit of new members is the projects cockpit canopy which is one of only two that i know of. The other on the right (photo Grimreaper) is at the Robertsbridge Aviation Society & Museum in Sussex, interestingly enough in the same county that mine was found in.

        The very early pre-production canopies had a nasty tendency to collapse or implode in flight, and it was during one such incident that test pilot Nick Goodhart, who later went on to invent the mirror deck landing system for aircraft carriers before becoming a rear admiral, was almost decapitated and killed by one of these six feet long canopies detaching in flight and striking his head. He eventually managed to regain control of the aircraft and land safely.

        Production S.4 canopies were strengthened with a more substantial base and strips of a white material bonded to the inside of the canopy together with thicker bands of perspex to help improve rigidity (as pictured), and it was with this type that the Wyvern entered FAA service in 1953. These were subsequently replaced with an improved all metal framed version fitted with a one piece perspex moulding during the types upgrade in 1956 that was also specifically designed so that straight through ejections were possible, (there are also examples of straight through ejections taking place with the earlier type, but i don't think it was designed with this in mind).

        Does anyone know of any other Wyvern canopies that have survived, especially of the later type with the metal frame and rear fairing?

              Wyvern

              Only slightly damaged and looking abit like an armoured window from a fortified church, this 21mm thick Wyvern front screen panel will be used to replace a totally smashed one and make a second complete windscreen unit.

              I'm still looking for the curved hinged panel that goes onto the front of the windscreen itself if anyone knows of one kicking around (similar design to the Canberra PR.9 so i'm told).

                Are these recent finds, or parts you have found over the years ?.

                Great projects by the way .

                  Its a new acquisition Bob. The laminated front panel as pictured was part of another windscreen unit i collected during the week. But due to severe corrosion in the units metal frame the panel was being distorted and forced out under pressure, so i decided to remove it completely to avoid any further damage.

                    Sturgeon

                    Although at the moment its not much to look at i've started to make up a little display of representative instruments, equipment etc as used and positioned in a Short Sturgeon's cockpit.

                    Apart from the pilots notes and a couple of photos sent to me of Sturgeon cockpit sections in the scrapyard at Forres in 1964, finding information and reference material on the cockpit is as expected proving extremely difficult.

                    The same problem was encountered by Tony Buttler whilst he was compiling photos for the excellent book 'STURGEON, TARGET-TUG EXTRAORDINAIRE'. Both the FAAM research facility and Ulster Aviation Collection have so far drawn a blank too.

                    Next port of call me thinks will have to be Bombardier Shorts themselves. Unless of course any of you guys have a schedule of spare parts gathering dust?

                      Just a quick update, as thanks to Bruce my left side panel mock-up from post #50 has now gained a Radio Altitude Indicator.

                      Now only one instrument and three switches to find

                            I'm looking for a Dunlop AH8763 27J/249 spade grip if anyone has a nice and original one at a reasonable price? I believe its a less sought after type without the selectric firing button - but just having the large 'press to transmit' button positioned to the left of top centre.

                            Also thanks to Jack Ruskin i now have the undercarriage position indicator that i was looking for, as shown in post #62

                                Not a great one Jon but here goes. Another angle can be seen in the pic in post #69.

                                  Thanks to this thread and some help from a member of the RAF Museum i have managed to track down a fascimile of the Sturgeon schedule of spare parts. Inside of which it lists the pilots seat as a plastic type AS.2101. Does anyone know if this is a generic type seat (I guess member Air Ministry might know)?

                                  Edit.. here's a view of the back of the pilots seat

                                        Martin, probably a long shot but are they by any chance viewable online?

                                          I don`t think so at the moment,they`re still going through stuff( ALOT)..but I think that is what they`re aiming for.
