Data from set of original DLW diagrams offered for sale on Ebay in March 2013.
A builder's list compiled by the late Robert Lemuth and supplied by Allen Stanley from this extensive Rail Data Collection showed the following locomotives fitted with the same cylinderxstroke combination and 29" drivers: Peru 2174-2175 February 1930 Peru Cerro de Pasco Copper 30-31 USA 2180 March 1930 Defiance Coal Company, Defiance, NM 2 (Lemuth's list recorded adhesion and engine weights as 43,000 lb/19,504 kg for the Peruvian locomotives, 42,000 lb/19,050 kg for the DCC engine.)
