Double Bass String ID

[Matt Ides]

Three types of strings I can’t identify. Any help would be appreciated. Some of these string are old.

Also older she with packaging La Dorsa (?)

Round wounds look like guts. The black ones are chinese strings that are no good. I've seen them on student basses.

The set with the blue silks look just like my Jargar Mediums

Nope, they're not Jargars.
They don't use the same type of balls.
I bought my first set of Jargars over 30 years ago, and they still use the same balls nowadays.
