Bread-Bakers v110.n037.6

I enjoy the Lahey no-knead bread and its simplicity of baking in a 
Dutch oven.  However, I would like to make a rectangular loaf for 
slicing for sandwiches.  Since the covered cast iron pots used in the 
Lahey method are round Dutch oven type all one can achieve is a round 
loaf.  Does anyone know of a source for a rectangular cast iron or 
cast aluminum bread pan, with cover, that could be used to make a 
regular sandwich bread loaf ??

Thanks for help.
