I am just now starting to add some streetcars to my collection, so if this subject has been dealt with before, please pardon the repetition.
The MTH Railking Washington Sightseer PCC streetcar appears to have added roof vents in a full-length housing. is this the only MTH PCC with this feature? Many of Boston's PCCs were modified in a similar way, and this would be a good starting point for a repaint.
