I know that there are two versions of the XG 1 model. The second model is XG-1(n). Here are pictures. I would assume that the XG 7 model was followed by a XG-7 model. However everywhere you look, the XG 7 model is advertised with a XG-7 manual. But you won't find a picture of an XG-7At least I can't. Hmmmpppffff!
