1st 175 Guns TAC Mark

1st Guns TAC MarkThe 1st 155mm Guns TAC Mark is plastered all over this site but I can’t seem to find an image of the 1st 175mm Guns TAC Mark. Does anyone know what it looked like? Did they simply replace the “155” with “175”? The shape and color of the mark was determined by the fact that it was part of 1st FAG, which was part of Force Troops Pacific, so that would probable make the most sense but I can’t make out a TAC mark on any of the photo’s I have of the 175 (M107) guns.
