Interesting cockpit lever with the words Hohe Drezahl ( High Speed) on the outside edge and Niedgrige Drezahl (Low Speed) cast into the inside edge.
Painted black and made of alloy it has a 20mm tube clamp at the bottom and no cable attachment points. The knob is offset. There are some markings but a dent in the wrong place obscures the R8 number.It could be an X9 or XX9 aircraft ?
I assume it is a mechanical prop pitch or throttle lever from an early/pre war aircraft.
No other details apart from it came from the middle of Russia so unlikely a sea plane.
Most throttle levers I can see are straight metal with plastic half rounds bolted to them. Also with the canted lever and a 20mm rod to be turned so no way for a second one side by side.
The prop pitch levers are mainly electrical with some mechanical but they dont lever in this way.
Anyone know what it is from ?

Thank you James.
I wonder whether the hydraulic ground tester (above) had an RPM adjuster.

“Drehzahl” is better translated as “rpms” than speed.
It’s literally “turning count”.
So what you have is “High revs/Low revs” and not high/low speed.
Hope this helps.

I have found this reference that has similar numbers. Hebel with gerate numbers 19-5XX are known
Hydraulisches Bodenprüfgerät, Vorläufige Beschreibung und Bedienungsvorschrift, Anford.-Zeichen Fl E 050901, Gerätenummer 19-509 A-1, Inhalt: Allgemeines, Beschreibung, Bedienung, Wartung, Störungen und Behebung. 1940, 40 S.

The gerate number 19-509 matches with this part although the 6059 does not match the FL number….

All german vehicles had either steel fittings or foot pedals. None I can find had levers like this for speed (not even for aggressive windscreen wipers).
Most likely candidates (from a design) are the late 30’s trainers/recons with multiple levers and gashebel on the cockpit sides.

Thanks Soggy _ I am open to all suggestions – but it doesn’t match with any of the usual German vehicle culprits that I have checked so far and it is lightweight alloy not steel.
I did have a look at powered turrets but again nothing obvious.

Interesting, but if you will forgive an uninformed observation, it seems more like a vehicle (AFV?) casting than aviation related? I don’t know why I would suggest that, it’s just a ‘feeling’ and probably wrong, but it looks too ‘chunky’ for cockpit-ware.
All the best with it…
