Thanks Snautzer for the info ! . I knew Preschona the kraftstofventil - the other Preschona Bf110- 1940 item is more simular to oxygencrane.
The AEG parts sadly no response ,the small has something with current in the inside are numbers 1-2-3 in brown.

I will post some new pictures ,hope to hear from you.
