Hello,
please, could anyone help me to identify attached Registering instruments? It should be the Barohraph (on the left I think) and Registering speedmeter (on the right pic side). They both should be "Luftwaffe geräte" used for registration of flying parameters. Barograph is not the snandard type because of its electrical connection. They were used in Research flying center in Sudetten after WWII. If you know what type they are, please let me know. (Unfortunally this is only one known photo).

Here is a barograph with electric:

I'm afraid that this is another type of barograph :-(. The one on the picture has electric connector in lower left corner and the fixing holes are on the sides not on the top and bottom.

So finally I found the producer of those instruments. It was Czechoslovakian company PREMA PRAHA (socialised in1948). Here is a picture from its catalogue and its logo which can be found on instruments in Me-262 cabine.




Unfortunatelly I'm not able to find more pics.

Instrumente dieses tschechischen Herstellers waren definitiv nicht in der Me 262 eingebaut! Vielleicht im tschechischen Nachbau der Me 262, aber nicht in den Versionen bis Mai 1945!

I'm sorry, I wasn't accurate enough. They were used during flight tests of post war Czechoslovakian Avia S-92.2 during 1948.
