>>8086588Like anon said, they're for the Barraki. It's dated to 2005, so they must be very early concept designs.
Though some people think this pic may be potential concept stuff for the unmade 2010 line. It lacks the Bonkle logo, so it could be for something else, but it looks more like Constraction than System, and it's dated 2008, which would place it in the right timeframe for 2010 concepts.
