This model consists of the parts to assemble a complete cast iron water tank, including a plate for the base and an extra plate which could be used as a top plate. Corner seam sections are included. The model is based on photos and drawings of the Hassel Island water tank shown in the HABS/HAERS archives: http://www.loc.gov/pictures/collection/hh/item/vi0026.photos.167075p/ It has not yet been printed. Sandstone "brick" piers similar to those in the photos are in development.
In 1:43.5 this tank is prototypically 6' x 6' x 6'.
In 1:32 this tank is 4'5" x 4'5" (1.35m x 1.35m)
In 1:24 this tank is 3'3" x 3'3" (1.0m x 1.0m)
*PLEASE NOTE* In the one test cast, the side panels have proven thin enough to warp inwards during shipping. Application of heat as described in many articles online should be sufficient to remove any warpage that may occur.
