    Yes and a Stinson Reliant landing in the background at one point.

    The Viastra II in the photo was fitted with a direct drive Jupiter VI to port and a geared Jupiter XI.F to starboard. The VI’s were taken from DH Hercules and often fitted due to the many failures of the XI in desert conditions, it is recorded that performance didn’t change much except for cruise consumption, according to Andrews and Morgan (Putnams). The engine underneath appears to be a VI.

    I suppose we’ll now get hectored for corrupting the thread.

    Just to confirm that it’s not off a Breda 25 as it’s prop diameter is 252 cm. I’d forgotten that I have copies of the engineering notes for this aeroplane.

    Good thinking TT. Another more common type to use the Lynx was the Breda 25.

    I believe that it might be this one. The original was a poor small contact print which was amongst a number of photos I bought a little while ago. Another photo was of a Hamilcar which was at Farnborough.

    Well if I’m reading the data right it was originally 244 cm dia (seven and a bit feet) and it’s off a 200 CV powered engine yet it appears to be British rotation. (Lynx Avro?) I wonder if it’s something to do with 6 Sqn who disbanded at Coltishall and who spent much of their service in the middle east. Though some of the bases don’t match.

    Oh dear, Hawker Hudsons. (On the IWM caption). IWM really need some people to advise and spot these mistakes. Interesting photo never the less. 800 Lockheed A29’s and A29A’s were initially allocated to the RAF for transport duties, according to USA Military Aircraft (Putnams).

    One difference between the Lockheed 14 and some of the other examples mooted here is that it was a successful and useful aeroplane before it was militarized and the others were designed from the outset as “fighting machines” all of which splendidly failed to achieve that goal.

    Ventura’s as well as Hudson’s and the Halifax used the BP C. 2 type turret. The BP type C.1 from which the C.2 evolved was basically the front half of the Hudson turret and was the nose turret of the Halifax B.II. a large number were also mounted on wheels as Turret trainers at gunnery schools. As an over water GR type the BP turret gave the gunner of the Hudson an very useful arc of vision.

    It might also be a Genet II as the II and IIa were essentially the same as the Genet 1 (65 hp) with the vertical cylinder uppermost, but were more powerful, (80 hp) by having a raised compression ratio.
    To add to this list. The Genet II and IIa powered a number of production types such as the Robinson Redwing, DH 60 Moth, Bluebird II and III, Avro Avian II, Westland Widgeon III as well as the earlier II.and some one off’s such as Klemm L.25, and Parnall Imp and the Anec IV Missel Thrush. The Missel Thrush crashed in Peebleshire during the 1928 Kings Cup. A wheel still exists, could this be another relic of the mountain. The sole British registered Monocoupe 60 had a Genet II and was scrapped at Gatwick in 1947.

    With little else to go on but the internals, the key to anything else would be to trace it’s sales path. Do you know who the Vendor (you obtained it off) is and if so try to elicit where he got it.

    It is Armstrong Siddeley and I still back my first guess at a Genet 1. or as we don’t have a precise crank throw a Genet II. Both engines were used in many UK light planes, many of which were scrapped during the war and i think that the post war Gatwick dump had some Genet engined types.

    It would be interesting to know where your vendor acquired it. Armstrong’s used quite a bit of standardization, for instance the Mongoose, Lynx and Jaguar shared the same cylinder.. A Genet II engined Fleet Finch was stored in a garage on the A.1 at Closterworth. (between Peterborough and Grantham).

    I still think it’s a Genet 1 crank and rods. The stamped words confirm that it’s probably British. If you can measure the throw of the crank from the centre of the prop shaft to the centre of the Master rod gudgeon pin, then this will give us a bit more info. The Genet 1 had a 4″ stroke and the Major was 4.5″ and I think the Mongoose was 5.5″.
