This large Walco commercial chafer # WL54130CR includes the food and water pans shown in the photos AND also includes the unused parts to hold the heat source (Sterno) which was missing at the time the photos were taken.  The chafer is made from 18/10 stainless steel polished to a mirror finish on the exterior and designed for high end hotels and banquet halls.  The roll top opens to 180 deg. and is tension controllable to prevent slam downs, the handle, foot ends and tension knobs are chrome plated die cast metal.  It has never been used, I installed the handle for the first time to take the photos, it will be back in the bag and the tension adjusters will be removed for shipping.  There are a couple of small light scuff marks from over ten years in storage, the chrome accents on the rear feet have some slight pitting and the tight spots could use a better cleaning and polish.  If you need more than one, I have a second identical unit that is not listed and will be under a separate listing after this set sells. 

All of the restaurant supply companies I found selling this item have it priced over $600.00 just for the chafer without the pans, they are not included in their price.  This sale "includes the Walco food & water pans shown and the heat container", the Walco site also lists that item separately.  Dia. 19.75", height 17.5".
