European Tram in a movie, but which one..

Good morning.
In a TV-Movie (produced in Germany) I saw recently this tram

The scenes were filmed in a scrapyard, apparenty in southern Germany (Bavaria).
The destination sign says "Route 8, Harras" which leads to Munich,
but the car itself hat no similarities with any known Munich tram, except the color.
What puzzles me is, it is obviously a single-ended car with modernized windows
and a very characteristic flat front. I found some slightly similar looking cars,
but no one is fitting.
The bell on the upper right front indicates that it "could be" a former trailer car,
were the conductor-bells on or near the car's end were common, but that leads
to the hypothesis that the route number and the destination signs were added later,
to make it look like a motor car. It was not uncommon that some scrap-yard owners
bought old trams just for fun or as storage room and modified them.
Has anybody an idea? I'm running out of ideas, so I carried this odd question to a more
american focused forum.
Thankyou.

It's obviously an old tram, quite unlike a modern vehicle. There are probably few or no systems that would still operate such a tram in regular service. Film makers often have access to various models stored for the purpose.

Thanks.
But in this case, it is unlikely that a scrapyard was staged just for filming purposes.
It's not Hollywood here.

It appears to be a Munich f2 class trailer car

Not really... the f2 has rounded corners and the car I am searching for has a flat front.
The more I think I believe that it is in fact a very good crafted "mock up".
