I got this and some other cast iron from my grand mother she 96 and she had got from her mom that past away at 101 years old. This is very old piece it even has a rope looking braid made into the casting on lid. Thanks for looking

Wish you had a better picture. Can't really make out any details. Any chance of a better shot?

Looks like camera lent is dirty

Better pictures would be helpful, but from the description of the markings and the picture, I'd say that's Columbus Iron Works.

Ok I will dig it back out take few more in better lighting.

Yeah, Columbus Iron Works grill, missing the grill bowl, grate and the firebox base.

Doug you were right, I pulled up the CIW from best I can tell they called it a railroad roaster 1920's. Dead on match to the pictures. At least I have my answer. Thanks For all the input.
