This is my 14270 with serial number starting with S. The tiny grains of tritium do emit light.
I don't have a picture of it, but my 16610 with the same serial number starting with S does not emit tritium micro-grains.
I used my 16610 a lot and my 14270 not so much.
I think this has something to do with the fact that the tiny grains of tritium do not emit light.
