They certainly did!
Plenty of time has passed since this thread was active…
I am happy to say the information received has been put in good use.
The model Lynx is now finished, work on the rest of my model is proceeding rather well.
As the building continues, I have come across another difficulty, so I am again writing for assistance.
I am lacking positive information on the instrument panel of the Avro N. I already have all known drawings, some good some bad, but I have a good idea about the layout.
What I am missing is photographs, which are much more definitve. I could not find any of the instrument panels. The sole sutviving example in the Danish Museum is heavily modified, so not good as a basis either, as can be seen from the attached pictures.
Can anyone help please? Even photographs of contemporary panels from similar aircraft will do, or even of individual instruments such as altimeter indicator, airspeed indicator, RM indicator, oil pressure, watch etc…
Better than nothing…
Thanks,
George Kandylakis
thanks for all your input.
TT, Email sent, I do not know if it comes directly to you, I went for both possibilities…
George
Well, that wasn’t long, was it?
A more careful look at the photographs brought out the first problem. The engine in Sywell and that in Denmark are different ones…
The Sywell, as the one in my section drawing have cylinders with approx 23 colling fins.
The one in Denmark has 34… Also the crankcase is markedly different.
Checking old Flight advertisments for the Lynx, I also count 23-24 fins, for an engine captioned as 180 h.p Lynx. The rather blurry pictures of the Greek Avros also seem to be 23, plus in a Flight issue of 1925-26 the engine is stated as 180h.p. So this seems to be a good match.
My only problem is I need to discharge all the information of the Danish engine, as it is probably a different model. Maybe a 240 hp?
But the caption of the Sywell plaque also states 240hp supercharged?
Help???
If, as it seems, the Sywell engine and the one usd by the greek Avros is one and the same, then I wouldn’t mind some more pictures, if it is not too much of a trouble. Feel free to improvise about the number and angles…
Thanks (again) in advance
George
Thank you both very much for the input. Enough information to work with but I might come back for any more specific questions… Now that I have the source…
As a small contribution, here are a few pics of the Danish Avro engine
George
and the diameter of the mounting plate…
Yes please!
If it is a sectioned lynx, then it would be great if you could make some pictures with a measuring tape along the length of the crankcase and the cylinder section.
I think I could figure out the rest..
Thank you,
George
Hi John,
that is excellent, thank you very much !
George
Hi john,
thanks for the info on the magazine… Any chance of identifying the actual issue so that I can look for it? The photograph is from a solid modeller’s forum, I am trying to contact the original poster, but no success yet…
Matt,
you are quite correct, I noticed these details, that is why I like this drawing very much. It looks like a clean job by the dratftsman.
George
Another question, in case anybody recognises it.
While searching for drawings, I came across the old Aeromodeller drawings, but also a picture odf a more modern and rather better detailed 3-view by A. Granger. Unfortunately, I do not know the source. It seems to be a booklet or a magazine. Any ideas?
Thank you both for your replies.
Mike (I assume…), that was some very helpful analysis. At least it logically confirms the known fact, despite the photographic evidence opening possible questions…
longshot (no assumptions…), thank you for the link. Yes, Eau de Nil is the closest one would call Pale or Light Green…In case of no further information I could work with that… I do think there must be Titanine charts of the period somewhere, I will keep looking…
No, no model yet, I have enough on my hands as it is…

The photo only came up recently and there is no harm researching parallel to building… Of course, it is very easy to get distracted, if something interesting and fully documented comes along…
