I forgot British standard fasteners…They are measured in furlongs or something right?

Never hit a SP rivet in my life (they are almost just a legend now 🙂 )

SP80 = AN430AD i think (the round head).

Rivets do correspond to AN/MS/NAS in sizing, with diameter in 1/32 and length in 1/16 inch.
So SP80-405 would be 1/8″ dia 5/16″ long.
I’ve got a fair stock of AGS rivets SP70/71/78/80, AS 2200 series plus Avdel and MBC. It’s not that scarce.

Hi Welsh HTE,

The way we describe the aircraft is in an airworthy condition, but not allowed to fly, this is due to the cost of recertifying all the components, even though we have all the documentation for the aircraft.

Peter, Any spares would be appreciated, we do have quite a large amount, but you never know what you might need, anything is usefull!

The HDU was succesfully installed yesterday with no major snags, we are now going to carry out the functional tests to ensure everything on the aircraft side is OK. Will post some photos soon.

So, how many FI units does the airframe have?
Good luck with the HDU functionals.

Great photo’s and good to see you’ve got a HDU as well.
Takes me back (quite) a few years when they still resided at Marham.

The team that tackled Foxhunter was not not over-endowed with up-to-date air-to-air experience. Their Ferranti opposite numbers had some interesting views on where the Foxhunter project went astray.

It is interesting to note that the Lightning was fitted with the AI 23 and the Tornado with the AI 24. It does show a certain lack of continuity in development.

The HP Victor in the background appears to have a serial number in the XL 18? or 19? range, which would make it very new at that time. So new, in fact, I suspect the picture may be later than stated (but I’m willing to be corrected on that as I have limited reference material). Also the tail of the Valiant appears to be peeping out behind the Vic – I don’t suppose you’ve got a shot of the two of them together?

You can see it is a B2 indicated by the RAT intakes, stubwing and the fin extension intake. I keep staring at the photo and I think I see a 1 at the end which would make it XL191.

She looks great, good job well done. Did you know that there is one part that is fitted in both the Halifax and Victor. One small bungee cord is exactly the same in both types.

Cheers

Check out the navigation lights, I think you might find a similarity.

I don’t know about the owner but I would be very happy to show off the cockpit of the only Victor to break the sound barrier if it was mine.

In one of the RR service manuals, it describes undoing the main bearing nuts to remove the crankshaft, the procedure requires a dial gauge to be located on the main bolt stud, and to slacken off a few thou at a time on each bolt (in a set order); I can just about understand the need for a dial gauge on assembly, but disassembly….

Possible distortion of the cap, it’s not unusual to have rather solid looking assemblies distort if they are dismantled wrongly.
