Help me identify these strings please.

These were installed on my bass by a previous owner whom unfortunately I cannot contact. The sound they produce was astonishing and I'm eager to find a couple of sets. The strings are roundwounds with silver (-ish) silk and the ball ends are black. Can't find them anywhere. If anyone can help with this I would really appreciate it.

Easy. Dean Markley Blue Steel (the stainless steel ones, not nickelplated). I used these for years at one point.

Thanks, man.
