Chimney HO Scale

this HO scale chimney was for use in a small 2 story section house.  In HO, I based the bricks on actual brick dimensions, although the morter joints have to be exagerated to show up in HO scale. In actual dimensions, its about 1/4" square and a little over 2" tall.  The intention is that the part can be cut off to appropriate length for mounting on a roof, or inserted through a hole in the roof.  Either way, use a bit of gray paper to model flashing and hide the joint.
