Fantastic Senior Argentina Officer's Hat - For What?

[rathbonemuseum]

Hi,

I bought this senior officer's hat on the bay thinking it migh be air force based on the color. But of course it is not. Air force would have had large 'wings' coming off of the main badge. So I think this is a senior officer's hat for the Army but possibly parade dress? I also think this dates from the 1940s. I am looking to sell or trade this hat and I would like to describe it correctly. Do you know what it is?
