Federation Commander

I've often seen reference to the "wing" or "bow" phasers on Klingon ships, but I'm unsure of which are which. For example, the D7 has a pair of single ph-2s with firing arcs of LF-L-RR and RF-R-LR, and a pair of double ph-2s with arcs L-LR and R-RR. Which are wing, and which are bow?

Bow phasers in the nose of the boom and usually FX or FA+. On the D7 these are 1-2-3.

Wing phasers are in the forward corners of the main hull. On the D7 these are 4 left and 5 right.

Waist phaser are besides the shuttle/apr/deckhouse. On the D7 these are 6-7 left and 8-9 right.
