ID these strings please!

Bought this Sandberg from Bass Bros. I like the strings!! Any idea what they are? I think they may be stainless steel as they are pretty bright!

The way that the winding stops with just the core going over the saddle makes me think these are Rotosound PSD or similar piano-wound strings.

GHS has similar set, I think it was named as contact core.

They might be the old Superwound Groundwound (Halfwound) set from 80s/early 90s...the winding colours used to match the packet colour and they were in a yellow packet as I recall.

Plenty of sustain off them..

Not Rotos because they have red silk. 
 

Not GHS because they have grey silk. 
 

I'm stumped.

I have asked Will at Bass Bros...no reply! He is a busy lad though!

I’m not really up on roundwounds but apparently fender 7150 had gold/yellow silks, could it be them 

[fretmeister]

Are they yellow silks?

 

 Could be Mark Bass. Their Andrew Gouche sig set has tapered / bare core at the bridge.

I bet it is these. Purple and Gold are his colours too, for the ball ends.

They look like Dean Markley SR 2000's.
