Pregunta a Dr. Carlos Balette

Hello I was 2 weeks ago in San Salvador. I am historian, living in Europe, Belgium. Do you have any relation with the Mr. Balette who was owner of this house made of steel plates, at the corner between Call Arce and Pasaje Morazan. I am searching details of the history of this house. When was it demolished is also unknown. If you know more, I would like to get in contact. Thanks in advance.
