There is some corrosion to the metal housing for the battery (I have removed the old battery) but it is still serviceable and although I have not tested it I see no reason why the system should not be in working order. There is the Tri-ang Lines brothers badge to the back and the paper electrics factory label to the underside (see photos). There is one widow absent (above the car port) and I think there should be two chimney stacks but there is only one present. All in all it is in very good condition showing only the expected age related wear and tear. It stands 16 3/4" tall and measures 18 3/4" x 10 3/4 at the base.The item "VINTAGE TRI-ANG DOLLS HOUSE WITH ELECTRICS ALL ORIGINAL INSIDE & OUT BLACK WINDO" is in sale since Sunday, December 29, 2019.
