3x8 raised flu pan with 3x4 front pan w/ reversible flow. Back pan is in excellent condition. Front pan needs some work. The hood was built for these pans and is one piece. Pans and hood were built in 2015 by A&A Metal. I bought new 3x9 rear pan with bigger flues and new front pan and needed different good to fit correctly. If you need an arch, A&A Metal can build you one at a reasonable price. I can get you in contact with them.
