Does anyone know the time line of Redline chainwheels.........?

So first there was bubble script.......this is from the redline site,  says 1979 for this one.

I've got one where the font is more like the style on the arm decal. That's the one that's puzzling me to know what era bike it may or may not be correct for, at a guess 85. Anyone know or got any other info? Thanks
