Identifying flatwound strings by silk and ball end colours?

[AnAnInginAneAnA]

So I was cleaning out my old parts bin, and found a set of flats (that I can't recall buying or owning) in a ziplock bag, and I was hoping somebody here could maybe identify them by the silks and ball ends.

 

They have red silks at both bridge and headstock ends, and the ball ends are Silver on the E, Green on the A, Black on teh D, and Bronze on the G.

 

Thanks in advance.
