Ok, cool. That still leaves me wondering what we should use for the ref= tag since what's on the pole is the only identifier and in reality that number isn't actually in the NaPTAN data (well it is but its buried). Looks to me that neither OSM nor Naptan have a full set of data for bus stops in the west mids.
