2007 or 2008-2011. My neighbor has a 2006 OTG that has the silver bucket. The black cans look fine on the black kettles i guess, but when it comes to red, blue, green, sage, brick red (non black) i like the silver cans. I entertained the thought of painting mine red to match my red kettle, but I fear that the paint would scratch off from use or flake off from heat.
