No responses???
Well, I guess nobody knows...Or...
Everybody knows and they think I'm a dummy for asking such a foolish question...
In any event, I already own the two in the middle (one is on my Nambu and the other is on a Luger) and I won the auction on the third one [green background] so whatever it is it'll go on the Lahti in the other thread...
Still, it would be nice to know why they're all different...
