OEM repos (sources.list) for Dell XPS 13 9380 with Bionic

Because of a tragic accident the sources.list on my XPS 13 9380 with Bionic 18.04.03 has been rm -r ...if you know what I mean.

Everything's in place and working but I don't remember (and can not find it anywhere) the name of the OEM repository that was in 'Software & Updates' in the 'Other Software' tab/list. It was there, I saw it a couple of times but didn't care to write it down...

Can anybody with a similar configuration do me a favor, look it up and post the name of it here? Thanks in advance.

Posting here the result of my investigation, the sources.list for XPS 13 9380 with i7 (code-name 'italia-whl'):
