Hi folks.

Again with the parts list (why do I accept these things anyway?).

Now I understand all the words, what I am trying to figure out is whether Träger is a brand name or whether it means a slow one or is it the bracket for the Umschaltfilter. I found "Trager LLC" in England, but that does not seem to fit.

Anybody seen anything like this before?

Thanks.
