Need help to ID cylinder Bf-110 and meter

[Harrie]

Hi guys,

Anybody know what kind of cilinder this ? It is from a Bf110 G-2 and is also used if i,am correct in the Fw190D-9 ,Ju87-D .
It,s designed especially for higher altitude and for using flaps ? .
Is this right ? .Anybody knows more about this ?.

What can be the other part [maybe altitude ?] also same Bf-110

The parts will be gifted to relatives of the pilot who will make a visit to me.

Any information will be much appreciated

Harrie
