Yesterday I purchased a "previously owned" 13708.   I would like to put "curtains" (white tape) on the inside of some of the windows, so I can model the quarters end of a Chapel Car.  The parts list/instruction sheet was not included with the car.  Where would I find out the correct way to open the car, and if Bachmann has extra curtains like the ones this model has in the windows between the seating area and the vestibules.You cannot view this attachment.
