Very-late-in-the-game Mikado produced in the last couple of years of Baldwin's steam-locomotive era. Simple, direct design in the middle of the 2/3-gauge 2-8-2 power spectrum with 9" (229 mm) piston valves.
tells us that this sextet was part of a steady importation of small Mikes of similar design to Guatemala from 1928 to 1948; see Locobase 15425. The International Railways of Central America (IRCA) were an amalgamation of many roads, including, apparently, the Agricola of Guatemala. Krupp and Baldwin were the manufacturers, with Baldwin delivering more than 30 after World War II.
