These are the strings that were on my new bass. Can anybody tell me what they are? Interesting that the silks are the same blue on the bridge end, but all different colors on the headstock end!  

 

DiAddario Slo-Wounds, maybe???
 
I know I've seen these before, but it was in the '90's, so I can't recall.

Definately Slo-Wounds.  They stopped making those.  Those were my favorite on my Series II.
