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.

The Chilean Air Force originally received 4 of these aircraft in 1944. All were allocated to Grupo 2 at Quintero and used as trainer for the future Vought OS-2U Kingfisher pilots. By the end of the 1950s only one example (registration number 500) remained airworthy (ex BuNo 0719). Suggested service colors (azure blue / intermediate blue with dark blue rudder) are shown in this graphic:

It was sold and used until 1980 as a glider tug by Santiago Gliders Club and Valparaiso Air Club. Shown here in her glider towing years:

It was then donated to the museum, where it is now seen on display with FACH markings and serial 001. Here is an outdoor photo from some time ago:

And another photo. This shot provides a great study of the “dash one” landing gear:
