Double Bass Help Identify strings

[Troiani]

Does anyone know what strings these are? The E and D are numbered, (4&2)
and the threads are color coded. There’s also a S stamped on the reverse side of the E and D strings.
Thanks!

They look like no name strings to me

Looks like very old Pirastro Flexocors solo gauge.
Like T-I uses, S means solo and numbers the strings themselves.
Very old Pirastros had a very thin metal wire interwoven onto the silk at the tuner end.
The color of the balls also match.
Nowadays they're black but were silvery back then.

Thank you! I knew this was the right place to ask. They’re for a student of mine that can’t afford new strings. If they are solo strings it’s perfect because her bass is not.
