As I happen to know what condition this was in before I can say you did a great job hypkx! Really nice. Anyone care for a hint of what it looked like before...

Its SA, I think row 2 will fit better than row 3 SA (which the DT keycap is). I only have two SA keycaps currently, but I will try row 2, from the look it can be the exact fit the row of the beamspring keycaps. The DT keycap will probably fit the row above them perfect.
