Was doing my usual browse of Ebay and came across this unremarkable looking Fairchild LCD.
It looked the same as a picture I have of a Tritium LCD, but there was no mention of the tritium illumination in the ad.
A bit of research indicated that if it has 3H engraved on the caseback, then it's one of the Tritium lumed versions...sure enough there it was!
So I clicked Buy it Now and am eagerly awaiting it's arrival!
No doubt the tritium will be very dull by now, but you can replace the 2 original flat tubes with a row of modern cylindrical tubes. So that's what I plan to do as someone else has done here:
Will probably stick to green though.
