Are these really Obligatos?

[Co.]

Today I got a package of used strings, that I ordered as Obligatos Orchestral tuning. When I unpacked them I noticed, they had a different color code, so I thought he sent me solo tuning strings, but then I remembered, Obligatos had black metal ballends and the usual Pirastro white felt.
These have brass ballends an green felt with an additional brass plate between the ballend and the felt.
So I looked up the Pirastro colorcode solo tuning strings and it also doesn't match.
The Tailpiece silks look exactly, and I mean exactly like Obligatos.
The pegbox silks are I yellow, II purple, III black, IV blue.
What are these strings?

The color code at the peg end seems like Corelli. (taking you mean 1 is G)
Furthermore, with Corelli, you'd get solid black with a red ring at the tailpiece, for 370TX series.
With Obligatos, this is a black twist over red silk.

These strings have a black twist over red silk. So are they Corellis?

I was wrong on the colors.
Obligatos are red twist on black silk indeed.
But the tone ID colors at the peg don't match Pirastro's.

Are you use it isn't orange instead of red?
That would make them Corelli 370F.

Otherwise I'm lost!

Obligatos are black twisted over a very dark red but the peg box colours are all wrong for Pirastro strings.

Francois may very well be right about them being Corellis.

Can you post a couple of decent photos?

I'm not best best with colors, so it might be a very reddish orange, definetly not dark red. I found this picture of a corelli string and it looks exactly like the E String I have: http://www.contrabass.co.uk/corelli_...te_tension.htm Very similar to Obligatos for the eye, unfortunately not for the hands or the ear.

They are indeed 370F then.
