tigerman - Not sure as I don't have first hand knowledge of the standard kit. I would assume that many of the parts are the same as many of the Panther kits. It looks as though this has twice as many parts as will be used... There is a sheet of PE, aluminum barrel, some metal side skirts, some clear vision port parts and 1-piece tracks. Plastic quality and detail of the parts is similar to current Smart Kits I have (non Panther). So appears to be a standard kit with some goodies thrown in? I'll post a pic of the sprues, etc. when I get started.
Looking forward to the GB as it will be my 1st.
