*original* original Flexocores?

[Thomas Erickson]

So I have had some of these old Flexocores for a long time now, and like them a lot - but, I'm not sure if they really are different from the current strings (in construction) or just "well aged". I think the matter has been discussed in passing here before, but I've never seen/heard what the deal is for sure -

Anyway, I guess they're the "Flexocores" that were made before the move to "Original Flexocores" and the Flexocore 92s? These have blueish-purple silk like today's Originals top and bottom, with an extra spiral of fine silver wire at the top. The D also has a bit of red silk at the tip. I have not measured them, but I would say they both feel and sound about halfway between the current Originals and the 92s in terms of thickness and darkness; they really do seem, somehow, to be a different string than either, though.

Anybody know - What are these strings, and how do they compare with the Flexocores we know today?
