This picture shows the firebox construction in progress.  Here we see the side and back walls of the firebox just about complete.  The firebox floor is complete with ashdump door installed.  The fascade and hearth are still to be built.  For earlier progression photos click here http://www.dmstorrschimney.com/our-soot-stories/firebox-reconstruction-in-reading-part-2-  As always do check back for more progression pictures on this project.
