Here is some findings of mine...
1. MX clear with new fonts switch top
Opened it , the switch stem seems to be the old one
I found that its not so scratchy, even quite smooth (It's my first batch of MX clear switches, I don't have other for comparison)
The stem surface look quite smooth, not so grainy feel as the old blacks
I have tried to lube it using dupont silicone lubricant /w teflon, the effects is minimal (still no match for zealios though)
I think this should be the retooled clears?
2. MX red with old fonts switch top
The switch stem is a new one with small gap at front
So it shall be the retooled one? However, I found this switch quite scratchy
3. MX black with new fonts switch top
The switch stem is a new one with small gap at front
New fonts and new stem, is it smooth? Yes, very smooth, much smoother than previous reds.
Conclusion?
It seems that the fonts on switch top is determining whether the switch is retooled or not
