T*O*F,
Lots of doubles had the triggers set up the same, whether right or left handed, as they are more or less directly one behind the other.
It is ( often) only the triggers themselves which are twisted to suit either right or left hands.
I do have one very early French/Spanish double, that has triggers set in this usual manner, and fairly widely spaced, yet it fits the left hand perfectly, and is Most awkward using the right hand! LOL.
