Thanks - I'm usually hopeless at identifying the machines posting here, but I thought that it might be SERGE written on the side of the fuselage, otherwise I wouldn't have had a clue.

My challenges in this thread don't tend to last very long.

I keep getting 403'd from the Sussex History Forum, however I approach it. I think I've had that problem before. Both with MS Edge and Firefox, and typing in the address as well as following a link. Does anyone have any suggestions, please?

FP, the link works for me on a Mac, with both Firefox and Safari.

For the benefit of anyone else who may have the same problem: I was able to follow the link, and read the interesting material, by using a VPN to pretend to be in England. I was then confronted with a cookies and privacy approval screen more elaborate than anything I've seen before. After accepting the default settings I was good to go. It is possible that the elaborate privacy arrangements object to people from overseas/outside the EU (legacy arrangements)/the colonies.

It appears that it may be more discriminatory than even you perceive, FlightlessParrot, if it allows access to Canadians but not Kiwis! However I'm glad that you got there in the end. You might also want to take a look at https://archives.imeche.org/archive/...t-de-bolotoff? (which, hopefully, will be easier of access). I think those photographs must be a relatively recent donation to the Institution of Mechanical Engineers because I didn't come across them when I was researching this subject a few years back.

Thank you for the link to the Mechanical Engineers. De Bolotoff seems to have been an interesting character, and presumably plausible.

I have never seen this photo before, but it looks a lot like Anthony Fokker's 'Spin' (or 'Spider').

You are correct, it is his second Spin, with Anthony sitting on the right - from the mechanical engineers website https://archives.imeche.org/archive/...nthony-fokker?

Told you that wouldn't last long - over to you.

To be precise it is the Spin replica. built in the mid 30's.
On a visit to the Aviodome in 1977 I was introduced to one of their ex Fokker employees who had helped build it.. IIRC was still in existence.

If it is the 1936 replica, it last flew in 1990 at Eindhoven Air Base:

Photo from Min.of Defense, coll. Van Beek
The pilot who flew it on that day had some interesting experiences during the flight. The 'Spin' only has an elevator and those small triangular rudders, no ailerons or wing warping. They flew it at the end of the day in dead calm weather but at one point he encountered a small thermal that bumped one wing up and he was probably holding his breath for quite some time while full rudder and the dihedral slowly levelled the wings again.

I'll go and find a new challenge.

Edit, how about this one:

Surrey Flying Services AL.1?

That's the one: https://en.wikipedia.org/wiki/Surrey..._Services_AL.1

You have control.

Thank you, Jhieminga. Here's another biplane from broadly the same era.

That’s staggering! :)

SNURK
The proportions are wrong; it looks as though they inserted the front cockpit, but left the wing attachment points at the same place on the fuselage, producing an ungainly s t r e t c h.

Is it a biplane or is it a parasol/low wing double monoplane, that is the question!

It's not as obscure as you might think. It even has a wikipedia entry all to itself.

Indeed it does: https://en.wikipedia.org/wiki/Volland_V-10

The Volland V-10 it is. Well done, Jhieminga. Your turn!

Thanks! Let's stay within the same era:
