Double Bass String ID

[Matt Ides]

All the strings have purple silks at both ends. I would say dominants but this does not have the typical ball end you find on Thomastiks. Ball end has 0 and 4 on it. Thanks for any help in identifiying this sting.

Looks like a very old Pirastro Flexocor E to me.

Agreed. Too bad the wrap is blown out.
