Bureau 0719 is on display in the new building of the Chile Museum of Aviation at the (now closed) Los Cerrillos Airport in Santiago, Chile. All indications are that this is currently the only intact N3N-1.

Suggested service colors (azure blue / intermediate blue with dark blue rudder) are shown in this graphic:
