Hi,
If you can't find any, I have a second hand one, coming from an old Italian car dealer here in Belgium, it was rather dirty at the outside of lying in his parts shed for many years already when his parts came to me, and then I kept the parts that way. I've cleaned the outside superficially with a moist rag but it still needs a better cleaning.
I have no idea a) whether it is in working condition and b) from what car it came, it was in a box with Lancia parts but it looks the same as yours and it has the correct Bosch number on the black plastic cover.
You can have it for 50 € + shipping- and Paypal costs if any. Definitelly no return on this !
I know it is a kind of bet but if interested, send me a PM.
Best Regards,
Thierry
