Bruhn Pitot

[john greenfield]

Hi guys

I need some decent pictures and dimensions of a Bruhn Pitot for my 1/2 scale Wien project. The Pitot sits very prominently on the nose of the aircraft and I would like to duplicate it.
Ideally something with dimensions would be best, I already have some poor quality grainy photos but they are not really clear enough to construct from.
Thanks

I shall expect it to be a working replica, full detail inside too.

Attached picture is from a Gövier II in Holland, The one I had my glider pilot lessons on. Picture taken in 1965
The reason for the picture is to show what is the front and back of the Bruhn Pitot
I have seen models with the Pitot the wrong way around, that is embarrassing.
The picture also shows the Pitot tube that was replacing the Bruhn Pitot in that time. (less drag . not sure why the Bruhn was left on the glider) This was a combination to measure speed, and static pressure .
it also had a third measure point what would be the early way to measure the Total energy (TEK tube is is called these days I believe) This would give you the real lift from thermals and not stick lift. How that was done mechanically is a total different story for an other topic maybe.
