Old stove parts?

[burghguy]

Am I correct in assuming these are parts from an old cast iron stove? I found them outside a workshop that had one inside. The long pieces are marked M54870 on top, the grate piece is a little over 12" across.

circular piece...would have been inside the stove at the bottom...we call it a riddle,it would sit on a centre spindle...and would be moved back and forth to let the ashes drop into the ash pan...value...very little,unless someone had a stove that needed this...then it would be like hens teeth...
