Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 66, pp. 190. See also the Pearcedale Conservation Park Brief Historical Summary of the Railroads in Peru at []. Works number was 54856 in June 1921.
The Peruvian Corporation, Ltd told Baldwin that they preferred Belpaire fireboxes after they took delivery of the Sojo, a 1917 Mogul shown in Locobase 15102. So it's not surprising that the square-shouldered furnace appeared on the Miraflores.
Its railway had a relatively long history with construction beginning in 1872, arriving in La Huaca in 1875. A year later, the line reached Viviate. Sullana (as it was then called) was reached in 1879. Piura took eight more years.
Even though the PC wouldn't officially own the P-P until 1929, it paid for this oil-burning Consolidation. Its firebox's brick arch was supported by two arch tubes measuring 9.6 sq ft (0.9 sq m).
