Bréguet's Pre-1914 ID Challenge #87

[YavorD]

I was able to found very little information about this aeroplane. May be someone knows something else about it.
Good luck!

Rules of engagement:

1. The thread title must be "Bréguet's Pre-1914 ID Challenge #......".
2. The score board, link and rules must be copied to the beginning of each thread, so that we know where we are. The score board and the correct answer to the challenge must also be placed at end of each thread.
3. The flying object must have been dreamt up before 1914 (no limit backwards in time ....).
4. There are no limits to the flying object for the pre-1914 series. There is no ruling that it must be flown, or completely built.
5. Machines which exist only as 'paper', that is absolutely no material has been cut to construct it, are excluded from this ID Challenge
6. The picture / drawing must show as much of the flying object as possible, but views showing the machine 'incomplete' are possible (with discretion).
7. Challenges which depict a machine already earlier presented are disqualified.
8. If there is any doubt as to the eligibility of a flying object for the challenge details should be PM'd to Breguet BEFORE the object is submitted.
9. Once someone has got 5 correct answers under their belt they belong to the ROYALTY. Once they belong to the ROYALTY they must wait 12hrs after the posting of the new challenge before they can post an answer.
10. To be eligible for correct ID an answer must include at least one characteristic of the aircraft that helped in its identification.
11. The first person to ID the challenge correctly gets to post the next challenge. If this can not be done for any reason Breguet himself will post the next challenge.
12. If a ROYALTY gives the correct answer too early, the challenge is over, he gets no point but has to post the next one. In lieu of the fact that the "novices" have in effect been "cheated" of their "exclusive" time that next post should be a relatively easy one. Anyone repeating the correct answer at the right time gets neither a point nor the right to post the next challenge.
13. The final arbitrator in relation to questions about the rules will be Breguet.

We are again in tsardom in the St. Petersburg area, from which archieve you presumable have the picture from.

This is the Biplane of Georgy Konstantinovich Demkin, a lawyer student then, built in 1911.
It was a tractor design like the early Sikorsky machines with two tail booms and a 24 hp Anzani engine but had wings of unequal span.

It is a little diffiult to find with the “Russian Aviation Museum”:

Biplane by Demkin

Only a few “short straight flights” were achieved with it.
Unfortunately apart form these few notes from V.B. Shavrov, I don’t have more of it.


Cheers

This is the sesquiplane designed and built by G.K. Demkin [Г.К.Демкин] in 1911. The machine can be recognized by its very steep sesquiplane design, a three- cylinder 25 hp Anzani with a tractor propeller and two tailbooms.Obviously a classical designed machine.

Unfortunately I could not fid any information about this machine and its flying career. Judging from the construction it must have been a good flyer, albeit a bit low powered with a 25 hp Anzani.

There is a very, very small reference to Demkin here, where it is stated that he held a shed at the airfield Gatchina at St. Petersburg.

Congratulations, Aquilius!
There is a slightly better copy of the same picture, I believe.
Thank you, Kees! Unfortunatelly, not much new information in this article.

Hi Yavor, it is really nice to see that the very mediocre (retouched) picture of this machine printed on flimsy Soviet paper in Shavrov can be substituted by a brilliant original contemporary print which has been held in archives during long years. There is hope that other mediocre rare pictures in Shavrov might also be available in high quality originals.

Right you are, Kees!
I am thinking about ordering some prints in order to see what will come out. Undecided which one yet ...
