Relay 9-9519 B : fitted on which type of aircraft ?

[gilles collaveri]

dear all

Recent diggings in Tarbes airport (South West of France) brought to light a plate of a relay with P/N 9-9519B

I could see here :

https://www.deutscheluftwaffe.de/?s=9-9519

that it was installed on Ju88.

But in Tarbes, we had JG101 with Bf109, FW190, Arado 96 and other Bucker Jungmeister..

So, my question is : on which type of aircraft was the relay 9-9519B fitted ?

Thanks for your expertise;

Gilles
