I don't know, but I suspect that all of those coils were actually made by Bosch
or one of their subsidiaries. They have factories
all over the world.

I owned a 71 Audi 100LS with all Bosch electrical system, and I have to say I
was not impressed with the quality. Some areas were
better than others, but overall I'd say it was only marginally better than
Lucas during the same period.
For example, Bosch fuses had to be changed periodically (even without being
overloaded), because otherwise they would fail due to
old age! The Bosch style fuses were just plastic forms with the fuse element
bent around the outside. The clip would pinch the
ends of the fuse element against the plastic form. Over time, the fuse element
would sag and eventually break from vibration and
heat. I finally discovered that Bussman made glass fuses that would fit the
Bosch fuse block, which solved the problem.
The Bosch version of a voltage stabilizer only lasted a few years before it
burned out. After the second one, I built my own from
much larger American components and never had a failure again.
The relay for the rear window defog grid was mounted under the hood; and used
phenolic for the base (instead of the more expensive
but more effective fiberglass). It got to where it would turn the grid on with
the key off, only when conditions were just right.
Fought that one for many months, before I just happened to walk by the car one
evening and notice the light glowing on the dash!
I also owned a VW Rabbit (aka Golf) from the same period, and it suffered from
similar issues. Its favorite trick was turning the
dome light back on after you had left the car, to run the battery down.
