Sonores is an older string from Gerold Genssler. I think Hervé Jeanne has a sound example on his string sound examples website (link in the stickies).
As nice as it is that Gerold develops his strings further, he drops old designs, so I'm afraid you won't be able together these old strings again. I talked to a local bass player who uses Gerolds strings and he told me he won't be able to get his old set from Gerold again, getting a newly designed set that Gerold recommended to him but which was significantly different from the old one.
I honestly don't know alot about these strings, bought it from a TBer. It's called a Sonores 2011 Basso, so probably similar to the 2015 Basso. It fit my 104 cm bass, so it could work.
