He may have sent the same request to other people with shots of the helicopter as well. The shots that get on A.net are generally no good for modelers as they need close-up, detail shots. About all they could do with a side-on shot is figure out how to make decals of the logo.
Although in a slightly different situation, I was asked for photos of an aircraft that I do have access to and was requested that I got some close ups for this person. I did so, and although they were not used for any commercial gain... this chap paid me for my efforts. He too was building a model.
