Etch-Brass 'Compass Bars' for 55mm round AW bases.
The Compass Bar marks the way that the base/figure is facing as well as its 180 degree front arc.
It is particularly useful on figures where the stance or weapon means that your figure cannot face the way that you want it to be facing and be touching scenery to get the cover bonus. It also prevents arguments over which way a figure is facing or precisely where its 180 degree front arc is.
The bars are accurate to within 0.1mm and denote the full front arc to the edge of the brass - anything behind that brass is behind the front 180degree arc.
