Double Bass String ID help needed

[JC Pat]

I have some old strings I can’t ID. I’ve checked Gollihur and don’t see a match. I don’t remember where I even got them…
See attached pictures.
Thanks!

By the red tailpiece silks I'd guess Spiros, but by the peg box silks I'd guess a mixture of tensions. Stark G, Solo E, maybe a Weich A and I have no idea what the grey D is. Whether they are S42s or 3885s would only be known by their actual gauge or full string length.

Could also be another make altogether, but the red tailpiece silks sort of shout Spiros.

They appear to be pre-D'Addario Super Sensitive Red Labels

Absolutely Red Labels. When wiring up a rusted-out muffler, accept no substitutes.

Appreciate the corrections there!!! They pre-date my experience.

Mystery solved! Thanks everyone. They actually don’t sound too bad arco…
