Ah ok, so it seems the AB/ab theyre using here is a completely seperate convention than the A to E grids. The capital A and B refer to if the stand is short, long or automatic, while the lowercase Ill have to check when I get off work. I think this could be another slot we can add to the stand infoboxea with a proper source.
