Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 15090)

Data from set of original DLW diagrams offered for sale on Ebay in March 2013.

The data for heating surface area and tube count or diameter are inconsistent. As laid out in the diagram, the evaporative heating surface area should add up to 1,458 sq ft.(135.45 sq m). It's possible that the tube diameter was actually 1 3/4" (44.5 mm), which would generate a total much closer to that given in the diagram.
