TTC Nylon Blue

These nylon blues seem like they are almost as old as the TTC Orange I posted a little while ago, I don't know if it's the same generation of switch or not, but they definitely seem like it. They have a relatively weak click too which I find happens with old/dirty clickies. 

I don't have actual specs but I'm gonna paste L Series Blue specs assuming they are the same.
