Not exactly MS but can any cello players help me ??

I've been given some cello strings and have managed to identify two as Synoxa (I was told they were all very good quality) but two remain unidentified. They both have burnt orange (or possibly red) with a narrow black band spiral winding at the tailpiece end, with a black collar at either end of this winding, ball is dark nickel coloured, winding at the peg end of one is royal blue, the other is a funny olive-brown colour. I would say both are G but the outer casing can vary no end in thickness according to the quality (silver wound, steel wound etc.) Can anyone identify this make for me please? I've tried googling but no listings have the right tailpiece winding. I've ruled out Jarger, Larssen, Evah P.

I'm too embarrassed to ask at the local luthier shop!
